The Oonah Formation appeared between . It has three sections, Mount Bischoff Inlier, the Ramsay River Inlier and the Dundas Inlier. The Success Creek Group from the Cryogenian has diamictite, quartz sandstone (Dalcoath Formation), and mudstone. It includes the Renison Bell Formation named after the Renison Bell mine.

The Causey Pike Fault has been recognised across the entire outcrop of the Lake District inlier, extending about 35 km from near Ennerdale Bridge in the west, to near Troutbeck in the east. A possible continuation of the fault to the east has been recognised in the Cross Fell inlier, where it also juxtaposes two differing parts of the Skiddaw Group.

Despite the multiple reworking that has affected Lewisian-like gneisses within the Moine they show evidence of a common history, although with some important differences. The largest, the Glenelg-Attadale inlier, shows evidence of eclogite facies metamorphism within both of the tectonically juxtaposed units that make up the inlier, thought to be associated with crustal thickening during a Paleoproterozoic event at about 1.7 Ga and the Grenvillian orogenic event respectively.

The Windsor Group is also exposed at Ingonish and Ingonish Beach. The Cabot Trail then doglegs to the north, crossing the Wilkie Brook Fault Zone, and entering the southernmost extent of the Blair River Inlier. The inlier is bounded by the Wilkie Brook Fault Zone on the east and the Red River Fault Zone on the southwest near Lone Shieling. The fault zones are marked by a zone of sheared rocks characterized by mylonite.

An inlier is an area of older rocks surrounded by younger rocks. Inliers are typically formed by the erosion of overlying younger rocks to reveal a limited exposure of the older underlying rocks. Faulting or folding may also contribute to the observed outcrop pattern. A classic example from Great Britain is that of the inlier of folded Ordovician and Silurian rocks at Horton in Ribblesdale in North Yorkshire which are surrounded by the younger flat-lying Carboniferous Limestone.

The Usk Inlier is a domed outcrop of rock strata of Silurian age in Monmouthshire in south-eastern Wales. It is located in the countryside between the towns of Caerleon and Pontypool and the village of Raglan. The longer axis of the dome or 'pericline', often referred to as the Usk Anticline, is aligned north-south. The inlier is largely surrounded by a sequence of Old Red Sandstone rocks of Devonian age, though both these and the Silurian rocks are largely obscured by superficial deposits.

The Andersons Creek Ultramafic Complex is west of Beaconsfield and east of the inlier with serpentinite, pyroxenite, gabbro and a sliver of oolitic chert introduced as a fault bounded block. To the west of the Badger Head Inlier is the Port Sorell Formation, a tectonic mélange of marine sediments and dolerite. Frenchmans Cap consisting of Precambrian quartzite In the Tyennan block, the Precambrian basement that forms the central core of Tasmania there are two formations. First, the Oonah Formation contains turbidite with quartz sandstone interbedded with siltstone deposited by gravity flows.

The whole North Pennines AONB, of which the Inlier forms part, is in fact of such interest to geologists that in 2003 it was designated a Geopark under a Unesco programme to promote public interest in geology. From an agricultural perspective, however, the Geopark is simply an area of poorly drained grazing that becomes progressively less useful as its altitude increases. Nevertheless, the lower slopes of the inlier are still sufficiently valuable to be enclosed, largely with drystone walling, and are used for grazing sheep and cattle. Fell ponies are also raised here.

It represents the easternmost extent of the Flintshire Coalfield. An inlier of upper Carboniferous rocks occurs to the south of Chester though it too is obscured by superficial deposits. Carboniferous strata underlies the entire Cheshire basin at depth.
|
|
The Motton Spilite lies on top of the chert. It consists of pillow lava, massive lava flows, sediments made from volcanic fragments, and chert breccia. The basalt is an ocean floor type. The Badger Head Inlier consists of deformed Burnie Formation.

The oldest rocks in Senegal are Archean or Proterozoic Birimian, commonly found throughout much of West Africa. Birimian rock units include the metabasic, meta-andesite, breccia and greywacke of the Mako Series, Diale Series meta-basites, red jasper, conglomerate, schist and marble, as well as the schist, greywacke and conglomerates of the Dalema Series. In the Kedougou inlier, these volcanic and sedimentary rocks were intruded by granite plutons in the Paleoproterozoic, during the Eburnean orogeny between 2 billion and 1.8 billion years ago. In southeastern Senegal, the Neoproterozoic Madina-Kouta Basin outcrops along the edge of the inlier.

|
In the Cross Fell inlier, the basal Dufton Shale Formation is followed by the Swindale Limestone Formation and the Ashgill Formation. In the Keisley area, the uppermost part of the Dent Group is represented by the highly fossiliferous Keisley Limestone Formation, exposed in the core of an anticline.
|
|
Felsic volcanic rock flanks the basin in the southwest and it is fragmented by numerous small faults. The Sharon Syenite, exposed just south of Franklin on I-495 indicates this, with a high-degree of fracturing. In fact, an inlier of Dedham Granite splits the formation in two in the southwest.

The central Australian desert lies south of these savannas and grasslands. The grasslands are mostly used for cattle grazing and are home to some threatened species of plants and animals. The higher areas of Mount Isa and the Selwyn Range, known as the Mount Isa Inlier, have their own unique wildlife.

The Komba Basin, bounded by the Kedougou inlier, Madina-Kouta Basin and eastern edge of the Bassaris branch contains the horizontal sedimentary rocks of the Early Cambrian Mali Group. The basin has a northern extension, known as the Faleme Basin is filled with chert, limestone and tillite potentially related to the glaciations of the Paleozoic.

Along the eastern margin, the geology of the Coen-Yambo Inlier is complex, with volcanic, metamorphic and acid intrusive rocks. The subregion of the Battle Camp Sandstones, formed from deeply dissected plateaus, lies in the south of the region, with the Laura Lowlands, composed of sands and silts, and colluvial and alluvial clays, lying adjacent.

These are matched by the Murton Formation (grey slates and thin sandstones) and the Kirkland Formation (mudstones with tuffs and lavas) at Cross Fell. The Buttermere Formation is interpreted as an olistostrome. The Tarn Moor and Kirkland Formations contain some volcaniclastic rocks. The inlier to the south at Black Combe contains the wackes of the Knott Hill Formation.

The lower part of the succession is dominantly andesitic. Locally in the western part, the lowest formation is the non-volcanic sandstones of the Latterbarrow Formation. In the Furness Inlier the Greenscoe Tuff Formation is the lowermost unit. In the southwest at Millom Park the Whinny Bank Tuff Formation is the lowermost unit, overlain by the Po House Tuff Formation.

The Whitchurch Sand Formation is a geological formation, in England. part of the Wealden Group, it is preserved as an inlier in hills in Buckinghamshire, Oxfordshire and Wiltshire. It was deposited in the Valanginian stage of the Early Cretaceous. The lithology largely consists of unconsolidated fine-medium grained sand with isolated bodies of limonite cemented sandstone, with localised beds of siltstone and mudstone.

Cabbage ghost gum occurs on red earth soils, often along watercourses. In Western Australia it is found in the Central Kimberley, Dampierland, Great Sandy Desert, Northern Kimberley, Ord Victoria Plain, Pilbara, Tanami and Victoria Bonaparte IBRA bioregions. In the Northern Territory it is found in the Davenport Murchison Ranges, Gulf Fall and Uplands, Mitchell Grass Downs, Mount Isa Inlier and Sturt Plateau IBRA bioregions.

These sources were in due course depleted or became uneconomic. The former cement works at Eastgate, until recently run by Lafarge, was based on an inlier of limestone. The site recently gained planning permission to form a visitor complex showcasing an eco-village using alternative technology, including a "hot rocks" water heating system. The underlying granite has been drilled and reports confirm their presence.

The Petermann orogeny was a mountain building event in the Neoproterozoic through the early Cambrian, 580 to 540 million years ago. The event exhumed the Musgrave Inlier, which divides the Officer Basin and Amadeus Basin in Australia. The orogeny is preserved in the Petermann Thrust Complex, with Mesoproterozoic granite and gneiss crystalline basement rocks, the Mt. Harris basalt, quartz-rich Bloods Range Beds and the Dean Quartzite.

Following unprecedented public pressure, the South Australian government announced on 22 July 2011 that mining would be banned forever in Arkaroola, with the aim of national and World Heritage listing. Mining companies have since threatened legal action against the government. Protection of Arkaroola from mining, including Mount Gee and the Mount Painter inlier, is provided by the Arkaroola Protection Act 2012, which created the Arkaroola Protection Area.

Rocks of Cambrian age occur most extensively in an inlier in Merionethshire where the up-arched rocks of the Harlech Dome form the Rhinogs. The Harlech Grits Group comprises sandstones, mudstones and greywackes forms the eroded core of the dome and within this sequence it is specifically the greywackes of the 'Rhinog Formation' which provides the higher hills. Cambrian rocks are also to be found in north Pembrokeshire, Anglesey and Llŷn.

The Precambrian basement in Queensland is west of the Tasman Line. It includes elements such as the Mount Isa Orogen and the Georgetown Inlier. The Mount Isa Orogen started with sediments, volcanics and intrusive rocks, and was deformed and metamorphosed during the Barramundi Orogeny 1870 Mya. Sedimentary layers formed on top, firstly felsic volcanic rocks from 1870 to 1850 Mya. Shallow water sediments formed from 1790 to 1705 Mya.

The location has long been visited by geology students and experts. Another example from South Wales is the Usk Inlier in Monmouthshire where Silurian age rocks are upfolded amidst Old Red Sandstone rocks of Devonian age. A similar outcrop pattern which results from movement on a thrust fault followed by erosion may be termed a window. Conversely an outlier is an area of younger rock completely surrounded by older rocks.
|
|
Outlier removal methods seek to pre- process the set of highly corrupted correspondences before estimating the spatial transformation. The motivation of outlier removal is to significantly reduce the number of outlier correspondences, while maintaining inlier correspondences, so that optimization over the transformation becomes easier and more efficient (e.g., RANSAC works poorly when the outlier ratio is above 95\% but performs quite well when outlier ratio is below 50\%).

Para Wirra Conservation Park lies entirely within an inlier of crystalline basement rock which extends southwards to Torrens Gorge. It is part of a more extensively exposed Precambrian rock mass, the oldest in the Mount Lofty Ranges. In the extreme west of the park there are undifferentiated metamorphic, mostly very micaceous rocks (schists), and gneisses. A zone of distinctive layered or banded quartz- feldspar rich rocks (gneisses) extends though the central portion of the park.

Unlike the Carboniferous Limestone landscapes typical of much of the Yorkshire Dales and Orton Fells, the range is formed from lower Palaeozoic slates and gritstones. An inlier of Ashgill age rocks of the Ordovician Dent Group in the vicinity of Backside Beck in the east The Howgill Fells www.yorkshire- dales.com are the oldest rocks in the range whilst the oldest Silurian rocks are the laminated siltstones of the Llandovery age Stockdale Group.

Lime makes an excellent mortar for sandstone buildings. Spread on the land it also reduces the acidity of soil and improves its fertility. Further to the north still, sandwiched between these intake fields and the steep slopes of the Pennine escarpment itself lies a complex geological zone known as the Cross Fell Inlier (see Burgess and Wadge). It consists of a lens of older rocks faulted upwards between the much younger layers that bound it.
|

Immediately above the village, this area is known as Red Carle. Still further to the north, the steep fellsides above the Inlier are unenclosed and grazed exclusively by sheep. In the past this would perhaps be best described as "ranching" as, in the summer the sheep would range freely over the top of the Pennine escarpment and down into Teesdale. Regular "gathers" would be held to round them up for dipping and shearing.

The Pennine Fault System is a NW-SE trending zone of faulting that forms the southwestern boundary to the Pennines in Cumbria. It was formed as a normal fault during Permian rifting, bounding the Vale of Eden basin, which has a half-graben geometry. It links through to the Dent Fault at its southeastern end. Rocks of Ordovician and Silurian age outcrop between the two main strands of the fault, forming the Cross Fell inlier.

The oldest rocks in Sudan are igneous and metamorphic inlier areas formed in the Precambrian and reactivated by the Pan-African orogeny. Examples include the Nuba mountains, Darfur block and the rocks beneath the Nubian and Bayuda deserts. In the two deserts, metasedimentary rocks were intruded by granitoids and turned to migmatite during the Pan-African orogeny. The Red Sea Hills preserve gneiss, metamorphosed to amphibolite grade in the sequence of metamorphic facies and metasediments together with ophiolite assemblages.

The Gulf Plains, which lie south and southeast of the Gulf, are mostly open grasslands of bluegrass (Dichanthium spp.). In the southwestern Gulf Plains, along the northern edge of the Mount Isa Inlier, there is a narrow belt of Eucalyptus and Melaleuca woodlands, with a grassy understory dominated by Chrysopogon fallax. In the southeastern Gulf Plains close to the Einasleigh Uplands, there are Eucalyptus woodlands, and low woodlands of Melaleuca with the grasses Aristida spp. and Chrysopogon fallax.

The main portion of the village is formed on the unique 'Bowerchalke greensand inlier' (an area of older rock completely surrounded by younger layers), highlighted in green on the adjacent map. It is not immediately obvious to the naked eye or on the standard Ordnance Survey maps with 10 metre contourswww.streetmap.co.uk but the apex is strikingly characterised by the 'island' drawn on the Andrews 1773 map. Its presence can be detected in the friable sandy soils in the centre of the village.

The Isan orogeny affected the Mount Isa Inlier in what is now Australia between 1.65 and 1.50 billion years ago in the Proterozoic. Deformation from the event is widespread and complex in the Eastern Fold Belt, with no consensus on timing and sub-events as of 2017. To date, most research has focused on the Snake Creek Anticline, Selwyn zone and Mary Kathleen Domain. At the end of the orogeny, massive A-type granitoids intruded with the Williams- Naraku Batholith.

The deposit is in Paleoproterozoic to Mesoproterozoic (2500-1000 mya) metamorphosed sedimentary rocks, known as the "Soldier's Cap Group", and is overlain by approximately of Cretaceous and more recent overburden. The deposit was discovered as result of an aeromagnetic survey of the Soldiers Cap Group in the eastern Mount Isa inlier. The area was selected for survey based upon extrapolations from known prospects and associated lithostratigraphy. In other words, the rocks were the same as other known prospects, only slightly more deeply buried.

Occasionally, enrichment in the unusual trace elements will result in crystallisation of equally unusual and rare minerals such as beryl, tourmaline, columbite, tantalite, zinnwaldite and so forth. In most cases, there is no particular genetic significance to the presence of rare mineralogy within a pegmatite, however it is possible to see some causative and genetic links between, say, tourmaline-bearing granite dikes and tourmaline-bearing pegmatites within the area of influence of a composite granite intrusion (Mount Isa Inlier, Queensland, Australia).

Water from the moors above Angram and Scar House drains into the reservoirs, which in turn feed the River Nidd. Below Scar House dam the Nidd flows east then turns south, and shortly after disappears underground through a series of small fissures in the exposed limestone inlier. All the water from the various fissures enters the large stream passage of Manchester Hole. The underground stream can be followed along an impressive 3 to 4 sq m passage to the equally impressive massive blockfall cavern of the Main Chamber.

The Hunter-Bowen event produced a ~3,000 km long structural foredeep above a Late Carboniferous and Palaeozoic margin to the weakly consolidated Australian continental mass which was part of the Gondwana Supercontinent at this time; the orogen developed to the east of the Palaeozoic Lachlan Orogen and the Proterozoic terranes of the Mount Isa Inlier. Before the orogeny the rocks of the coastal area were formed. During Late Carboniferous there was a continental margin with an oceanic trench subducting the ocean floor off the coast. To the east there was a magmatic arc.

Then it gets curiouser. Rock very similar to the WEMB (including a type called blueschist) is also found in the San Juan Islands, and along the West Coast fault on the west side of Vancouver Island. This suggests that the OWL was once a strike-slip fault, possibly a continental margin, along which terranes moved from the southeast. But similar rock also occurs in the Rimrock Lake Inlier, about 75 km south of the OWL and just west of the projected trace of the SCF, and also in the Klamath Mountains of southwestern Oregon.

The ecoregion is bounded on the north and east by tropical savanna ecoregions – the Victoria Plains tropical savanna to the northeast, the Carpentaria tropical savanna to the north, the Einasleigh Uplands savanna to the northeast, and the Brigalow tropical savanna to the east. More arid ecoregions lie to west and south – the Great Sandy-Tanami desert to the southwest, the Simpson Desert to the south, and the Eastern Australia mulga shrublands to the southeast. The ecoregion includes three IBRA regions – Mitchell Grass Downs, Mount Isa Inlier, and Desert Uplands.

In the Northern Fells of the Lake District, the Skiddaw Group comprises five formations of which the earliest/lowest is the Bitter Beck Formation. This is succeeded by the Watch Hill Formation, then the Hope Beck, Loweswater and Kirk Stile Formations in ascending order. The inlier at Cross Fell comprises just the Catterpallot Formation, a wacke sandstone which is the rough equivalent of the Watch Hill Formation, itself a wacke sandstone as is the Loweswater Formation. Within the Central Fells are the Buttermere Formation and the overlying Tarn Moor Formation.

The Inverclyde Group is present in a couple of outliers immediately north of the Highland Boundary Fault to the east and west of Loch Lomond. The eastern outlier forms the ground just to the north of Conic Hill and is assigned to the Kinnesswood Formation which consists of sandstones, often conglomeratic at their base, together with mudstones and cornstones (nodular carbonates). The Ballaggan Formation which includes mudstones and siltstones within which are thin beds (or sometimes just nodules) of ferroan dolomite, traditionally referred to as ‘cementstones’, is represented by a very small inlier on the park's southwestern boundary.

The closest 'unique greensand inlier' is near Andover in Hampshire. Surrounding the greensand is a ring of younger Lower Cretaceous Chalk which is about 100 million years old (darker blue on the adjacent map). The chalk was formed in warm, shallow, well oxygenated waters from the remains of micro-organisms (coccolithophores), over millions of years. At this time the Atlantic Ocean was about 100 miles wide and Ireland, Scotland, Wales and Somerset were a single island with rivers draining their nutrients into the warm sea that covered Wiltshire, Hampshire, the east of England, Northern France, Denmark and northern Germany.

The Hilton Mine is a zinc, lead and silver mine in northwestern Queensland, Australia, approximately north of the Mount Isa Mines. The mineralization is in the same grey dolomitic Urquhart Shale as the Mount Isa Mines deposit and a similar diagenesis is posited. It is one of five "supergiant" zinc, lead and silver mineralized deposits that have been found in the Mount Isa Inlier, six if one counts the high silver deposit at Cannington. In 1947, geologists working for Mount Isa Mines discovered the deposit and named it Hilton after Charlie Hilton, who, at the time, was the Mount Isa Mines manager.

Following the public outcry that resulted from Marathon Resources' misconduct in the Arkaroola Wilderness Sanctuary—including the illegal dumping of many tonnes of exploration waste in shallow pits, the South Australian government promised to introduce legislation to ban all mining activities in the sanctuary, with the Premier stating that "we have decided to give the region unprecedented protection". The protection enacted by the South Australian government prohibits any and all mining within in an area roughly coincident with the Arkaroola pastoral lease on which the Arkaroola Wilderness Sanctuary is located. This area includes Mount Gee and the Mount Painter inlier.

The rocks of Gowbarrow Fell were formed during the Ordovician period, roughly 460 million years ago. Two major groups of Ordovician rocks are represented on and around the fell: the Skiddaw Group and the Borrowdale Volcanic Group. \- may be viewed on the or on the BGS's iGeology smartphone app On the lower ground around the southern and eastern edges of the fell, faulting has exposed an inlier of mudstones from the Skiddaw Group. These rocks of the Tarn Moor Formation were formed in deep seas when occasional slides of coastal sediments were redeposited at greater depth.

The least squares formulation () is known to perform arbitrarily bad in the presence of outliers. An outlier correspondence is a pair of measurements s_i \leftrightarrow m_i that departs from the generative model (). In this case, one can consider a different generative model as follows:where if the i-th pair s_i \leftrightarrow m_i is an inlier, then it obeys the outlier-free model (), i.e., s_i is obtained from m_i by a spatial transformation plus some small noise; however, if the i-th pair s_i \leftrightarrow m_i is an outlier, then s_i can be any arbitrary vector o_i.

Most of the park is underlain by Kalahari Sands. In the north-west there are basalt lava flows of the Batoka Formation, stretching from south of Bumbusi to the Botswana border. In the north-central area, from Sinamatella going eastwards, there are granites and gneisses of the Kamativi-Dete Inlier and smaller inliers of these rocks are found within the basalts in the north-west. The north and north-west of the park are drained by the Deka and Lukosi rivers and their tributaries, and the far south of the park is drained by the Gwabadzabuya River, a tributary of the Nata River.

This was originally part of Gondwana, referred to as peri-Gondwanan Terrane, and through seafloor spreading separated from Gondwana, and collided with Laurentia during the Salinic Orogeny. The evidence of this collision, the closing of the Iapetus Ocean and the formation of the Iapetus Suture, is seen in the northwest part of the park where the Ganderia Terrane is connected with the Blair River Inlier, itself a remnant of the Laurentia continental margin, referred to as peri-Laurentian Terrane. Other terrane collisions followed, including the Avalonia Terrane during the Acadian orogeny, and the Meguma Terrane during the Neoacadian Orogeny. Then, between 340 and 300 Ma, Gondwana collided with Laurentia, forming Pangea.

The fourth stream originates in Hockley Woods, and is joined by a fifth in Hawkwell, on the edge of the Rochford Basin. Once they enter the basin, they all flow towards its centre, and join up near Rochford. The way in which they are all roughly parallel until they reach the basin, and then change direction, together with the presence of a small chalk inlier near Stambridge Mill, when the chalk layer throughout the area is between below sea level, has led Stratford to suggest that the Rochford Basin may be the result of an impact by an asteroid in the Late Oligocene or Early Miocene periods.

With the exception of a small inlier of Palaeocene sands at Witham, the lowest units of the Palaeogene sequence evident in Essex are the various Palaeocene/Eocene pebbly and shelly sand and clay formations of the Lambeth Group. Their outcrop reaches from Sudbury on the Norfolk border southwestwards to the Hertfordshire border at Bishop's Stortford. However the bedrock of the larger part of the county is formed by the silty clays and sandy clays of the succeeding Eocene age Harwich Formation which is ascribed to the Thames Group. Isolated patches of later Eocene sand, silt and clay occur in the area between Southend on Sea, Chelmsford and London.

Its main outcrop is in an east-west oriented band of country in the northern part of the Skiddaw range in the northern Lake District stretching from the village of Bothel east to form the hill of Binsey and further east, the more extensive Caldbeck Fells. A smaller outcrop underlies Greystoke Park just to the east of this area and forms Eycott Hill east of Mungrisdale. There is a further inlier at Melmerby Fell in the North Pennines. The outcrops are intensely faulted and in the Caldbeck area are crossed by numerous mineral veins yielding arsenic, barium, copper and lead which have been worked in the past.

Ascents: Apart from the lower slopes beside Aira Beck, around Dockray and alongside Ullswater, Watermillock Common is Open Access land. Paths across the common begin from the village of Dockray and from the two car parks on the A5091 road. One writer has claimed the ridge top near Common Fell "can be more of a wade than a walk", but this was not found to be so early in 2014 after an unusually wet winter. Geology: The oldest rocks found on the Watermillock Common ridge occur on the lower south eastern slopes (above Ullswater) where faulting has brought to the present surface an inlier of mudstone from the Tarn Moor Formation, the latest part of the Skiddaw Group.

Uranium exploration activity around Mount Gee circa 1969–71 Mount Gee is located in the northern Flinders Ranges within the Arkaroola Wilderness Sanctuary, and is part of the Mount Painter inlier. It was named after a mining warden, Lionel Gee.Mr Reg Sprigg cited by Recently Mount Gee came to prominence in 2008 - 2011 because of uranium exploration occurring in an area that was commonly (and mistakenly) believed at that time to be protected from all mineral exploration. This situation was altered in 2011 - 2012 when the Government of South Australia created the Arkaroola Protection Zone and passed the Arkaroola Protection Act (2012) which prohibits all mining activity in the Arkaroola Protection Zone.

The outer slopes are mainly of Carboniferous Limestone, with Devonian age Old Red Sandstone exposed as an inlier at the centre. Wookey Hole is a solutional cave mainly formed in the limestone by chemical weathering whereby naturally acidic groundwater dissolves the carbonate rocks, but it is unique in that the first part of the cave is formed in Triassic Dolomitic Conglomerate, a well-cemented fossil limestone scree representing the infill of a Triassic valley. The cave was formed under phreatic conditions i.e. below the local water table, but lowering base levels to which the subterranean drainage was flowing resulted in some passages being abandoned by the river, and there is evidence of a number of abandoned resurgences.

The Redbank Shear Zone in the Arunta Block, is a reverse sense shear zone dipping north at about 45 degrees, and was the major structural feature reactivated during the Alice Springs Orogeny. This shear zone is associated with one of the largest gravity anomalies known from continental interiors. The Redbank Shear Zone also accommodates 25% of the apparent shortening. Seismic and gravity data over the Arunta Inlier have provided a reasonable degree of constraint on the crustal architecture of this province and have demonstrated that the crust-mantle boundary is uplifted by 25 km along the lithospheric-scale Redbank Thrust Zone, and that this offset is sufficient to cause the relative gravity high.

Geological overview of Bowerchalke The Greensand inlier is a dome shaped area of hard, coarse, olive-green coloured sandstone rock which has had its covering of softer chalk eroded away by 60 million years of weathering since the region was lifted out of the sea. The Cretaceous Upper Greensand is about 120 million years old and was deposited in brackish, oxygen depleted, water when Bowerchalke was located at around 35 degrees north of the equator, roughly equivalent to southern Spain and Portugal. At that time it was still part of the supercontinent Pangea which was just starting to split and form the Atlantic Ocean. The nearest continuous Upper Greensand exposure is along the A30 in the Nadder valley at Fovant.

The vale lies along the eroded core of an anticline, a westward extension of the Mendip Axis, with a relatively thin covering of Mesozoic sediments folded upwards over an up-faulted horst of Palaeozoic rocks.Melville, R.V. & Freshney E.C. (4th Ed 1982), The Hampshire Basin and adjoining areas, British Regional Geology series, Institute of Geological Sciences, London: HMSO, p115 The floor of the vale is composed of Albian (Lower Cretaceous) beds of the Upper Greensand, exposed by removal of the overlying chalk. It is surrounded to the north and south by chalk scarps which close to the east near Burbage. There is also a small inlier of Greensand to the east at Shalbourne;Chilterns: Sheet 51N 02W Solid Geology, 1:250,000 Geological map series, British Geological Survey, Keyworth, 1991 this area drains northwards to the Kennet.

However, the Flaherty volcanics are suggested to have relationships with the Sutton Inlier and Haig sills. Geochemical indications suggest that the overlying Flaherty volcanics might also have relationships with the Povungnituk volcano-sedimentary group in the Cape Smith Belt, indicating the Flaherty volcanics might be 2,040 to 1,960 million years old. Sills on the Belcher and Snowy islands in Hudson Bay are dated to 1,870 million years old, indicating the 1,880 million-year-old magmatism also exists in this section of the Circum–Superior large igneous province. The Fox River Belt in northern Manitoba is composed of sediments, volcanics and sills. Fox River Belt sills and Molsen dikes are 1,883 million years old, but the Molsen dikes at the northwestern Superior craton margin intrude an older, 2,090 to 2,070 million-year-old dike swarm.

Aberdeen Coast Aberdeen Beach Being sited between two river mouths, the city has little natural exposure of bedrock. This leaves local geologists in a slight quandary: despite the high concentration of geoscientists in the area (courtesy of the oil industry), there is only a vague understanding of what underlies the city. To the south side of the city, coastal cliffs expose high-grade metamorphic rocks of the Grampian Group; to the southwest and west are extensive granites intruded into similar high-grade schists; to the north the metamorphics are intruded by gabbroic complexes instead. The small amount of geophysics done, and occasional building-related exposures, combined with small exposures in the banks of the River Don, suggest that it is actually sited on an inlier of Devonian "Old Red" sandstones and silts.

The Phoenix lander directly sampled water ice in shallow Martian soil on 31 July 2008. On 18 March 2013, NASA reported evidence from instruments on the Curiosity rover of mineral hydration, likely hydrated calcium sulfate, in several rock samples including the broken fragments of "Tintina" rock and "Sutton Inlier" rock as well as in veins and nodules in other rocks like "Knorr" rock and "Wernicke" rock. Analysis using the rover's DAN instrument provided evidence of subsurface water, amounting to as much as 4% water content, down to a depth of , during the rover's traverse from the Bradbury Landing site to the Yellowknife Bay area in the Glenelg terrain. In September 2015, NASA announced that they had found conclusive evidence of hydrated brine flows on recurring slope lineae, based on spectrometer readings of the darkened areas of slopes.

The North Pennines are formed from a succession largely of sedimentary rocks laid down during the Palaeozoic era, later intruded by the Whin Sill and affected by glaciation during the Quaternary period. Mud and volcanic ash deposited during the Ordovician and Silurian periods were buried and subsequently faulted and folded during the Caledonian orogeny, the mudstone becoming slaty. These rocks which are between 500 and 420 million years old are now exposed along the great scarp which defines the western edge of the area and also in an inlier in upper Teesdale. Unseen at the surface but proved in boreholes is the Weardale Granite, a batholith emplaced as molten rock into the slates and other rocks around 400 million years ago. Its presence beneath the region results in it being an upland area since granite is relatively less dense and therefore ‘buoys up’ the North Pennines.

Rocks dating from the Silurian period are, by one measure, the most significant for Wales’ landscape; a greater percentage of the country's land area is directly underlain by rocks of this age than any other. Much of central Wales is formed in Silurian sandstones and mudstones as is the more gentle landscape of central Monmouthshire where the Usk Anticline gives rise to the Usk Inlier. In the north it is the Ludlow age mudstones and sandstones of the Elwy and Nantglyn Formations which form the Clwydian Range,British Geological Survey 1999 Flint England and Wales sheet 108, 1:50,000 scale geological map and the Nantglyn Flags and Wenlockian Denbigh Grits which form the Denbigh Moors,British Geological Survey 1993 Corwen England and Wales sheet 120, 1:50,000 scale geological map Llantysilio Mountain and the Dee Valley around Llangollen.British Geological Survey 1994 Wrexham England and Wales sheet 121, 1:50,000 scale geological map (provisional) In west Wales, parts of south and central Pembrokeshire around Haverfordwest and Narberth and between Marloes and Daugleddau are formed by Llandovery aged mudstones, sandstones and conglomerates.

So far, the materials Curiosity has analyzed are consistent with the initial ideas of deposits in Gale Crater recording a transition through time from a wet to dry environment. In December 2012, NASA reported that Curiosity performed its first extensive soil analysis, revealing the presence of water molecules, sulfur and chlorine in the Martian soil. And in March 2013, NASA reported evidence of mineral hydration, likely hydrated calcium sulfate, in several rock samples including the broken fragments of "Tintina" rock and "Sutton Inlier" rock as well as in veins and nodules in other rocks like "Knorr" rock and "Wernicke" rock. Analysis using the rover's DAN instrument provided evidence of subsurface water, amounting to as much as 4% water content, down to a depth of , in the rover's traverse from the Bradbury Landing site to the Yellowknife Bay area in the Glenelg terrain. On September 26, 2013, NASA scientists reported the Mars Curiosity rover detected abundant chemically- bound water (1.5 to 3 weight percent) in soil samples at the Rocknest region of Aeolis Palus in Gale Crater.
