In the Balkan Peninsula, Potamon fluviatile is known to occur in Croatia, Montenegro, North Macedonia, Albania and Greece. There are four species of Potamon in the Balkans, and P. fluviatile is replaced by Potamon ibericum in northeastern Greece. In mainland Greece, P. fluviatile is found in the drainages of the Axios, Thyamis, Aheron and Arachthos, Pineiós, Piros-Tethreas, Pamisos and Evrotas rivers. In the Ionian Islands, P. fluviatile is known to occur at only one site on Corfu, as well as on Kefalonia, Lefkada and Zakynthos.

Potamon fluviatile is at the western distributional limit of the genus Potamon. Other species in the genus occur through Eastern Europe and the Middle East, and across Central Asia as far east as northwestern India. The populations of P. fluviatile on the Peloponnese, Kefalonia, and Zakynthos may represent a separate, cryptic species, and the population from the Peloponnese was described in 2010 as P. pelops. P. fluviatile was formerly divided into three subspecies: P. f.

Potamon fluviatile is a freshwater crab found in or near wooded streams, rivers and lakes in Southern Europe. It is an omnivore with broad ecological tolerances, and adults typically reach in size during their 10–12 year lifespan. They inhabit burrows and are aggressive, apparently outcompeting native crayfish. P. fluviatile has been harvested for food since classical antiquity, and is now threatened by overexploitation.

Fluviatile deposition extends from the point of freshwater input up to 9.7 km (6 mi) into the Bay, with its sediments more coarse. The transition stage between these two realms contains sediment mixes from the marine and fluviatile areas. The last recorded rate of sediment deposition was in 1936, with a recorded estimate of 23 cm (9.1 in) annually. However, deposition is subject to seasonal variations.

Sediments that are found within Yaquina Bay are derived from tertiary rocks from the Central Oregon Coast Range, Pleistocene marine sediments and estuarine deposits. These sediments have three realms of deposition; marine deposition, fluviatile, and an intermediate transition state called marine-fluviatile. Marine deposition is found within the initial 2.4 km (1.5 mi) of the estuary and is associated with average ocean salinity and turbulent mixing. The sediment is similar in texture to sand and other fine grains.

Valvata tricarinata is abundant in nearly all lacustrine and fluviatile deposits in North America of the Pleistocene period. The fossil shells are more variable than the Recent ones.Frank C. Baker. July 1921.

Potamon fluviatile has a generalist diet, feeding on vegetable debris, scraping algae from surfaces, or preying on frogs, tadpoles, and various invertebrates, such as insect larvae, snails or worms. No predator seems to specialise on P. fluviatile, but a number of animals take it opportunistically, including rats, foxes, weasels, birds of prey and jays. The most significant predator may be mankind, with individual prospectors able to catch 3,000 to 10,000 in one season. Adults occupy burrows, while smaller individuals shelter under stones.
|
|
The entrances to the burrows may be more than from the stream's edge and are always above water level. The burrows may be more than long, and probably serve to protect the crabs from extreme cold. Potamon fluviatile is an aggressive species, mostly attacking with the larger right claw, since 90% of individuals are right-handed. In the Tosco-Emilian Apennines, P. fluviatile is only found south of the watershed, in contrast with the crayfish Austropotamobius pallipes, which occurs on both sides on the mountains.

Potamon fluviatile is widely distributed in much of mainland Italy, especially in the provinces of Trento, Lombardy, Veneto, Liguria, Tuscany, Umbria, Lazio, Campania, Apulia, and Calabria, as well as on the island of Sicily. Although it used to be found as far north as Lake Garda, P. fluviatile no longer occurs north of the River Po. In 1997 a population of P. fluviatile was discovered under the ruins of Trajan's Forum in the heart of Rome, living in canals built by the Etruscans which connect to the Cloaca Maxima. Based on a genetic analysis, which demonstrated that these crabs were similar to those in Greece, researchers believe that they had been brought by the Greeks before the founding of the city, some 3000 years ago. The crabs' unusual size, up to , and longevity (up to 15 years) are also interpreted as evidence of a long-established population, by analogy with island gigantism.

His collection included 62 species not appearing in l'Histoire naturelle des Mollusques terrestres et fluviatiles de la France (the Natural History of Terrestrial and Fluviatile Molluscs of France) of Draparnaud and was consulted by Gaspard Louis André Michaud (1795–1880) when he wrote the supplement to this work.

Natio fluviatilis was found in northern Italy, natio tarantium in southern Italy, and nationes thessalonis, kühnelti and laconis were found in parts of Greece. The geographical distribution of natio leucosis was not reported, and it was suggested that a further (undescribed) tribe inhabited the Greek island of Andros. Despite this wealth of infraspecific taxa, they are rarely used by scientists, and some have questioned directly the value of defining infraspecific taxa within P. fluviatile. In 1990, the population on Malta was described as a separate subspecies, Potamon fluviatile lanfrancoi, and that taxon has become a conservation icon in Malta following its legal protection in 1993, although not all scientists recognise the taxon.

It overlies the Bald Peak Basalt formation, and underlies the Pleistocene epoch Leona Rhyolite formation. It is composed of siltstone, sandstone, and conglomerates. It has fluviatile and lacustrine deposits. Descending under the Bald Peak Basalt formation are the Pliocene epoch units of the Siesta Formation, Moraga Formation, and Orinda Formation.

Diaphanosoma fluviatile is a species of freshwater ctenopod in the family Sididae. Native to Central and South America, it has been found in lakes farther to the north. In 2008 it was reported to have been found in central Texas.López, Carlos; Soto, Luz Marina; Dávalos-Lind, Laura; Lind, Owen (2008).

The depositional environment of the structure is mainly deep- water marine (i.e. continental rise) comprising coarser grained turbidity currents and related high-concentration flows (grain flows, fluidized flows, liquefied flows). But dish structure can also be encountered in shallow-marine deposits and in fluviatile, lacustrine and delta environments.T. H. Nilsen et al. (1977).

The G. K. Warren Prize is awarded by the U.S. National Academy of Sciences "for noteworthy and distinguished accomplishment in fluviatile geology and closely related aspects of the geological sciences." Named in honor of Gouverneur Kemble Warren, it was first awarded in 1969 and has been awarded every four years since 1982.

Vegetation at the ponds includes amphibious bistort (Polygonum amphibium), common spike-rush (Eleocharis palustris), water horsetail (Equisetum fluviatile) and water crowfoot (Ranunculus aquatilis). The condition of New Hartley Ponds was judged to be favourable, and described as 'outstanding' in 2010, with concerns expressed as to newts getting trapped in gully pots on the New Hartley Road.

The life span of P. fluviatile is typically 10–12 years. Moulting does not occur in winter. Mating lasts between 30 min and 21 hours, with spawning usually taking place in August. Females carry the eggs on their pleopods (appendages on the abdomen) until they hatch directly into juvenile crabs, having passed through the larval stages inside the egg.

Potamon fluviatile is edible, as indicated by its alternative specific epithet edulis, and was known to the ancient Greeks; it is probably this species which they depicted on medals found at Agrigento, Sicily. More recently, the species was depicted on the 5¢ coin in the last series of Maltese coins before the introduction of the Euro there in 2007.

The gravelly deposits consist of mixture of slope scree, debris flow, and fluviatile or even torrential flow deposits. The finer grained, sandy deposits consist of eolian and playa lake deposits. The latter contain well-preserved, freshwater fossils. Numerous radiocarbon dates indicate that the bulk of these concordant sediments accumulated between 15,000 and 8,000 BP during the African humid period.

|
Although their ranges overlap, the two species do not inhabit the same water courses, apparently because the crab outcompetes the crayfish, which is therefore forced to live in less favourable locations where the crab cannot survive. Non-indigenous crayfish may pose a greater threat to P. fluviatile than native crayfish, although the greatest threats remain pollution, overfishing and the draining of wetlands.

The formation was defined in Erfurt-Melchendorf in 1830 by Franz Xaver Hofmann and named for the nearby town of Erfurt. The Erfurt Formation is underlain by the Upper Muschelkalk. The lower boundary to the Erfurt Formation is the "Lettenkohlensandstein" in northern Germany and the "Grenz-bone-beds" in southern Germany. The formation is a sequence of dolomite, lacustrine limestones, claystone, evaporites, and fluviatile sandstones.

Characterized by its very wide extension, it comprises sandur terraces and the floodplain of the Isar river. These most recent deposits overlie the Neogene Molasse basin of the Alpine Foreland, which in contrast comprises fine-grained fluviatile and lacustrine facies.

He contributed about seventy memoirs or papers between 1863 and 1913. His special interest went to paleoconchology and Recent mollusks, especially the terrestrial and fluviatile species. Though sometimes rumoured to have been a clergyman, Lechmere Guppy was, in fact, an agnostic. Guppy discovered the Guppy fish in Trinidad in 1866, and the fish was named Girardinus guppii in his honour by Albert C. L. G. Günther later that year.

Decapoda is represented by five species: two Astacidae (Austropotamobius torrentium and Astacus astacus), two Potamidae (Potamon fluviatile and Potamon ibericum), and one Atyidae (Atyaephyra stankoi, which was found in Lake Dojran). Bathynellacea is represented by three species: Bathynella natans, Parabathynella stygia, and Bathynella chappuisi. There are around 100 species of Myriapoda, including 18 endemic millipedes. There are 21 identified species of Entognatha, including 11 Collembola, eight Protura and two Diplura.

A wide variety of species occur, including water horsetail, Equisetum fluviatile, celery-leaved crowfoot, Ranunculus sceleratus, sharp-flowered rush, Juncus acutiflorus, and great pond sedge, Carex riparia. Great spearwort, Ranunculus lingua, a rarity in north-east England, is still found, but a number of other uncommon species have been lost in recent years, among them narrow-leaved water-parsnip, Berula erecta, water dropwort, Oenanthe fistulosa, and fringed water-lily, Nymphoides peltata.

Speleothem carbonates found in the caves have been subject to scientific studies. In fluviatile, spring, cave and soil environments microbial carbonates are important. In the biofilms and/or microbial mats, which are formed in the caves, the principal organisms associated are bacteria, particularly cyanobacteria, small algae and fungi. Petrographic analysis of a thin section has uncovered the presence of lithified structures and micrite, present as laminated to clotted with chocolate-brown blebs.

The sedimentary and metamorphic rocks that are present in the city are alluvium, fluviatile, lacuatine, pludal and beach deposits such as coral, stools, and beach rock. These are predominantly found along the coastal areas of Vigan. An important non-metallic mineral resource found in Vigan is the kind of clay that is used in making earthen jars locally called burnay. Earthenware of different uses and sizes are made of this kind of clay.

The central granite massifs consist of granite plutons, granodiorites and quartz diorites dating from 2.05 to 2.15 billion years ago. The north of French Guiana corresponds to a synclinorium composed of the Paramaca series on which sandstone and fluviatile conglomerates lie unconformably. Shield rocks in Guyana are all dated between 1.6 and 2.5 billion years ago. The Quaternary lands are located in the northern part of Guyana, near the coast, unconformably on the Paleozoic lands.

Gherardi became interested in crustaceans as a teen, when one of her friends had a tropical aquarium. She obtained a master's degree in Biology in 1979 from the University of Florence with a thesis on aggressive behaviour, dominance hierarchies and individual recognition in decapods. She gained her PhD in Animal Biology (Ethology) at the University of Florence with a dissertation on the eco-ethology of the freshwater crab Potamon fluviatile. Marco Vannini was her advisor for both degrees.

The Havelland Luch is mainly characterized by fen peat soils and peat soils that dried out after the land was drained. There are large areas where periglacial or fluviatile valley sands reach the surface. Mounds of ground moraine, more than ten metres high, pierce the surface of the luch, especially in the south, between the Nauen Plateau and the Ländchen Friesack. In places, the valley sands were covered by dunes during the early post-glacial period.

More tectonic uplift caused the sea to retreat one final time and during the Serravallian, Tortonian and Messinian/Pontian ages (late Miocene, 16 to 5 million years ago), the basin was in a continental facies again. The fluviatile sands and clays and fan conglomerates of this time form the Upper Freshwater Molasse (German: Obere Süsswassermolasse), the topmost molasse formation.Labhart (2005), pp. 20-24 Around 5 million years ago a phase of uplift occurred in the Alps.

The Supergroup consists of c.6000 m of sedimentary rocks with varying facies from basinal and distal turbidite to deltaic and fluviatile successions which exhibits a generally regressive sequence. The Longmyndian is separated into two main depositionally distinguishable units: the Stretton Group and the Wentnor Group. The succession is geographically positioned between the Pontesford-Linley Fault System and the Church Stretton Fault System which has been folded, possibly during the late Neoproterozoic, and is inferred to gently plunge to the south.

Samrong Sen (alternates: Somron-Seng, Somrong Seng, Somrong Sen, Som-Ron- Sen;Sophady (2007), p. 7 ) on the east bank of the Stueng Chinit River is a prehistoric archaeological site in the Kampong Chhnang Province, Cambodia. Consisting of a very large fluviatile shell midden, it flourished in particular from 1500 BC to 500 BC. Excavations at Samrong Sen, which started in the 1880s, have been described as the earliest prehistoric archaeological studies which gave credence to the concept of Southeast Asian Bronze Age.Miksic (2003), p.

The genus Equisetum as a whole, while concentrated in the non-tropical northern hemisphere, is near-cosmopolitan, being absent only from Antarctica, though they are not known to be native to Australia, New Zealand nor the islands of the Pacific. They are most common in northern North America (Canada and the northernmost United States), where the genus is represented by nine species (E. arvense, E. fluviatile, E. hyemale, E. laevigatum, E. palustre, E. pratense, E. scirpoides, E. sylvaticum', and E. variegatum).

The caps from Bedburg-Königshoven were found in fluviatile sediments, which, based on palynological evidence, are thought to date into the Preboreal.Behling, H and Street, M. 1999. Palaeoecological studies at the Mesolithic site at Bedburg-Königshoven near Cologne, Germany. Veget Hist Archaeobot (8): 273-285 This assumption is further supporter by the lithic typology occurring at the site, the faunal composition and two radiocarbon charcoal samples (KN-3998, KN3999) which place the archaeological horizon into a window of 9780±100 and 9600±100 BP[2] radiocarbon years.

The fossils are considered to be of non-flowering trees such as Chir, Deodar and Redwood, as only non- flowering plants (gymnosperms) existed during the geological time when the fossilization took place. The petrified wood is indicative of lush forests in a tropical warm and humid climate thriving 180 million years ago. Existence of fossils of gastropod shells also suggest that the region was a sea once upon a time. The claim is furthered by the fossils of stems of gymnosperms and fluviatile sediments and deposits.

The waterfall Galovački buk at the Upper Lakes The previously mentioned mechanical and chemical dissolution processes are regularly occurring natural phenomena. A unique process occurring at the Plitvice Lakes, however, is the sedimentation of water-bound chalk at certain places. With regard to other similar phenomena in the world, at Plitvice Lakes the sedimentation of chalk and the formation of tufa happens dynamically all along the watercourse and in various forms (fluviatile sedimentation). It is thus not a static phenomenon occurring at only single places.

Water crowfoot (Ranunculus aquatilis) and water plantain (Alisma plantago-aquatica) are found in pools left by river channel migration, and surrounding fens support horsetail (Equisetum fluviatile), bottle sedge (Carex rostrata) and meadowsweet (Filipendula ulmaria). The condition of Burnfoot River Shingle was judged to be unfavourable-declining in 2011. Invasive species are encroaching on the site in part because of lower levels of heavy metals in the contemporary river, (most mining having ceased in the watershed) and due to insufficient intervention. Wydon Nabb was judged favourable in the same year.

View of Lake Lawtonka, wind turbines, and plains from atop Mount Scott in Oklahoma The southern section of the Great Plains, between latitudes 35.5° and 25.5°, lies in western Texas, eastern New Mexico, and western Oklahoma. Like the central section, it is for the most part a dissected fluviatile plain. However, the lower lands which surround it on all sides place it in such strong relief that it stands up as a table-land, known from the time of Mexican occupation as the Llano Estacado. It measures roughly east-west and north-south.

Its age is Rupelian (early Oligocene, 34 to 28 million years old) and it consists of shallow marine sand, clay and marl. On top of this is the Lower Freshwater Molasse (German: Untere Süsswassermolasse) of Chattian and Aquitanian age (late Oligocene-early Miocene, 28 to 22 million years old). Due to a eustatic drop of the sea level combined by tectonic uplift, the basin was now above sea level. This second formation therefore consists of fluviatile sands and clays and huge alluvial fan systems (conglomerates and breccias) originating from the Alps to the south.

The Camarillas fossil site is in light brown clay and limestone rocks with fossil wood remains. The sedimentology is similar to that described in the Galve area, because the Camarillas Formation shows scarcely any lateral variations in facies within the Galve Sub-basin. The Camarillas Formation sandstone is fluviatile, and four groups of paleochannels are distinguished, the first towards the bottom of the succession. These channels become thinner towards the top, and this was interpreted by Díaz and Yébenes (1987) as evidence that there was an alluvial fan with a multichannel system.

In the freshwater streams that cross the Reserve live the river crab (Potamon fluviatile), the frog (Rana), the toad (Bufo bufo) and the newt (Triturus). Among the reptiles, there is the grass snake (Natrix natrix), as well as the green whip snake (Hierophis viridiflavus), the lizard (Lacertilia), the gecko (Tarentola mauritanica). The nocturnal fauna includes foxes (Vulpes vulpes), common pipistrelles (Pipistrellus pipistrellus), crested porcupines (Hystrix cristata) and hedgehogs (Erinaceus europaeus). Among the raptors, which often nest in the numerous farmhouses of the Reserve, there are the kestrel (Falco tinnunculus), the little owl (Athene noctua) and the peregrine falcon (Falco peregrinus).

In Britain and Ireland, this is one of the commonest pondweeds, occurring in almost any wet or semi-wet oligotrophic and / or acidic habitat so long as flow is not too rapid. It may be found in lakes, slow-flowing rivers, ponds, ditches, seeps and among bog mosses (Sphagnum). As its name suggests, it is common in areas of blanket bog but may also occur in secondary habitats such as unshaded drainage ditches in bogs and forest plantations. In British rivers it typically grows with other soft-water species such as Ranunculus flammula, Carex nigra, C. rostrata, Scapania undulata and Equisetum fluviatile.

Lacustrine and fluviatile mineral deposits occur intermingled with the above. Large areas of moving sands exist near Enotayevsk, where high dunes or barkhans have been formed. A narrow tract of land along the coast of the Caspian, known as the “hillocks of Baer,” is covered with hillocks elongated from west to east, perpendicularly to the coast-line, the spaces between them being filled with water or overgrown with thickets of reed, Salix, Ulmus campestris, almond trees, &c.; An archipelago of little islands is thus formed close to the shore by these mounds, which are backed on the N. and N.W. by strings of salt lakes, partly desiccated.

The recovered remains were deemed to belong in the same group O. pueri due to common ornamentation on the dermal cranial bones. The specimens were found at the Drummond Basin of Queensland, Australia, in the Middle Paddock site of the Duckabrook Formation. Estimated to be about 333 million years old, the Middle Paddock site is representative of “a shallow fluviatile or lacustrine environment,” which is a large body of water with sedimentary deposits made of slits, clays, and carbonates. The tetrapodal remains found here date back to Late Visean (early Carboniferous), towards the end of Romer’s Gap - a gap in the tetrapod fossil record.

The High Plains of Kansas, in the Smoky Hills near Nicodemus The central section of the Great Plains, between latitudes 42° and 36°, occupying eastern Colorado and western Kansas, is, briefly stated, for the most part a dissected fluviatile plain. That is, this section was once smoothly covered with a gently sloping plain of gravel and sand that had been spread far forward on a broad denuded area as a piedmont deposit by the rivers which issued from the mountains. Since then, it has been more or less dissected by the erosion of valleys. The central section of the plains thus presents a marked contrast to the northern section.

Cross-bedding in a fluviatile sandstone, Middle Old Red Sandstone (Devonian) on Bressay, Shetland Islands A flute cast, a type of sole marking, from the Book Cliffs of Utah Ripple marks formed by a current in a sandstone that was later tilted (Haßberge, Bavaria) Structures in sedimentary rocks can be divided into 'primary' structures (formed during deposition) and 'secondary' structures (formed after deposition). Unlike textures, structures are always large-scale features that can easily be studied in the field. Sedimentary structures can indicate something about the sedimentary environment or can serve to tell which side originally faced up where tectonics have tilted or overturned sedimentary layers. Sedimentary rocks are laid down in layers called beds or strata.

The hardy C. fluviatilis requires moist, shaded conditions for optimal growth. A small ground fern, the species is native to New Zealand and southeast Australia, a syntype common throughout the country in damp, shady areas in acidic, moist and boggy soil,BBC - Gardening - Plants - Plant Finder - Blechnum fluviatile 'Klwaklwak' beside streams in forest areas. This fern species occurs throughout much of New Zealand's forests, including much of the forested area of North Island; west, north and south coasts of South Island; and Stewart Island/Rakiura; moreover, it occurs in parts of the coastal forests of southeast Australia. Example understory flora associates in the mixed broadleaf/podocarp forests of Rakiura include Austroblechnum durum.

It is unlike them in composition, color, manner of bedding, and sedimentary history. Obviously the conditions of sedimentation changed in passing from the Wingate Sandstone formation to the Kayenta and from the Kayenta to the Navajo sandstone, but the nature and regional significance of the changes have not been determined. In some measured sections the transition from Wingate to Kayenta is gradual; the material in the basal Kayenta, beds seems to have been derived from the Wingate immediately below and redeposited with only the discordance characteristic of fluviatile sediments. But in many sections the contact between the two formations is unconformable; the basal Kayenta consists of conglomerate and lenticular sandstone that fills depressions eroded in the underlying beds.

The Swan coastal plain is characterised by a series of sand dune systems, the Quindalup dunes, the Spearwood dunes, and the Bassendean dunes, which run from west to east (in increasing age) from the coastline to the major faults which form the eastern boundary of the plain. The plain is bounded to the east by the Darling Scarp, to the north by a subsidiary fault running north-west from Bullsbrook, and to the south by the Collie-Naturaliste Scarp. The Pinjarra plain lies between the Bassendean dunes and the eastern scarps. Early work on all three dune systems considered them to have been formed at differing times by the deposition of sands carried by wind (aeolian and/or by river processes (fluviatile).

Forest streams, often lined by alder trees such as Alnus glutinosa, and grey sallow Salix cinerea, birch and oak, cut through the soft sandstone forming steep- sided valleys (ghylls) that are sheltered from winter frosts and remain humid in summer, creating conditions more familiar in the Atlantic-facing western coastal regions of Britain. Uncommon bryophytes such as the liverwort Nardia compressa and a range of ferns including the mountain fern Oreopteris limbosperma and the hay-scented buckler fern Dryopteris aemula thrive in this “Atlantic” microclimate. The damming of streams, digging for marl, and quarrying have produced several large ponds containing, particularly in former marl pits, localised rafts of broad-leaved pondweed Potamogeton natans, beds of bulrush (reedmace) Typha latifolia and water horsetail Equisetum fluviatile.

Born at Fougères in the Department of Ille-et-Vilaine, Heude became a Jesuit in 1856 and was ordained to the priesthood in 1867. He went to China in 1868. During the following years, he devoted all his time and energy to the studies of the natural history of Eastern Asia, traveling widely in China and other parts of Eastern Asia. The first fruits of his research concern the mollusks: his Conchyliologie fluviatile de la province de Nanking (et de la Chine centrale) was published in Paris between 1876 and 1885 in 10 volumes; his Notes sur le mollusques terrestres de la vallée du Fleuve Bleu can be found in the first volume of the Mémoires concernant l'histoire naturelle de l'Empire Chinois, founded by the Jesuits of Xujiahui, Shanghai in 1882.

Sources from the 14th to the 16th century counted the entire upper and lower geest west of the Jeetze plain and east of the Uelzen-Bevensen Bowl as well as the Dahlenburg Basin as the Drawehn. In this sense the term is defined as the main ridge of the East Hanoverian End Moraine including its foothills as well as the flatter eastern slopes to the fluviatile Lüchow plain. The northern end of the East Hanoverian End Moraine can be further subdivided into the Göhrde and Klötzie regions – with no clear cut transition or boundary. The Klötzie (also the Elbhöhen or "Elbe Heights") is the northern edge of the ridge, up to 70 metres high, which slopes steeply down to the glacial valley of the River Elbe between Hitzacker and Neu Darchau.

Mount Wood Homestead complex is today within Sturt National Park. The national park is representative of the shrub rangeland in western New South Wales, it provides one of the best examples of this land type in conjunction with wattle (Acacia spp.) dominated fluviatile and aeolian land types. The area, due to its size, is an important wildlife refuge, and has a significant species diversity including 246 native species, as well as a high diversity of landforms including Aeolian dune systems, Mitchell Grass Plains, the Jump Ups and Gibber Desert. The national park lies in the south-west of a vast bowl shaped depression which covers eastern central Australia, and is mainly covered by low undulating plains of Gibber Desert in the east or sand dunes in the west except for where it contains the south-western end of the Grey Range.

Western Australian Events The assembly of the Archaean Yilgarn and Pilbara cratons of Australia was initiated at ~2200 Ma during the first phases of the Capricorn orogen. The last stages of the 2770–2300 Ma Hamersley Basin on the southern margin of the Pilbara Craton are Palaeoproterozoic and record the last stable submarine-fluviatile environments between the two cratons prior to the rifting, contraction and assembly of the intracratonic ~1800 Ma Ashburton and Blair basins, the 1600–1070 Ma Edmund and Collier basins, the 1840–1620 Ma northern Gascoyne Complex, the 2000–1780 Ma Glenburgh Terrane in the southern Gascoyne Complex and the Errabiddy Shear Zone at the northwestern margin of the Yilgarn Craton. Between approximately 2000–1800 Ma, on the northern margin of the Yilgarn Craton, the c. 1890 Ma Narracoota Volcanics of the Bryah Basin formed in a transverse back-arc rift sag basin during collision.

While the northern section owes its smoothness to the removal of local gravels and sands from a formerly uneven surface by the action of degrading rivers and their inflowing tributaries, the southern section owes its smoothness to the deposition of imported gravels and sands upon a previously uneven surface by the action of aggrading rivers and their outgoing distributaries. The two sections are also alike in that residual eminences still here and there surmount the peneplain of the northern section, while the fluviatile plain of the central section completely buried the pre-existent relief. Exception to this statement must be made in the southwest, close to the mountains in southern Colorado, where some lava-capped mesas (Mesa de Maya, Raton Mesa) stand several thousand feet above the general plain level, and thus testify to the widespread erosion of this region before it was aggraded.
