However, the amount of PM10 have declined gradationally and increased from the year 2011 onwards.

This is overlain gradationally by ripple-laminated sandstone that is commonly bioturbated and contains mud drapes.

The Mitchell Settlement Formation is gradationally overlain by the Jacquet River Formation, which underlies a large area in the Jacquet River drainage basin.

Granite II gradationally underlies Granite I, although in places dyke-like bodies of Granite II have intruded Granite I and the overlying breccias.

The Blairmore Group unconformably overlies the Kootenay Group and is gradationally overlain by the Crowsnest Formation or, where the Crowsnest Formation is absent, is disconformably overlain by the Alberta Group. It is equivalent to the Luscar Group north of the Clearwater River and to the Mannville Group in the plains to the east.

The Pakowki Formation is abruptly overlain by the Milk River Formation and gradationally overlays the Judith River Formation or Foremost Formation. It is equivalent to the upper part of the Lea Park Formation in central Alberta. It is not differentiated from the Riding Mountain Formation to the east into eastern Saskatchewan and Manitoba.

The Elk Formation is the uppermost unit of the Kootenay Group. It gradationally and conformably overlies the Mist Mountain Formation. It is disconformably overlain by the Cadomin Formation and to the east it was truncated by pre- Cadomin erosion. To the north Elk strata may correlate with part of the Nikanassin Formation.

In places, red and grey shale may intertongue (interlock) with the Cleveland Shale extensively. In far eastern Ohio, the Bedford Shale thins by more than . Where the Cussewago Shale is also present, the Bedford Shale is usually less than and may be locally absent. In some areas, the Cleveland Shale is described as overstepped or unconformably overlaid gradationally by Berea Siltstone and sharply by Berea Sandstone.

The Hardyston unconformably overlies Precambrian crystalline basement rocks where it was deposited on an irregular surface and fills only the troughs or depressions. It gradationally underlies the Leithsville Formation of the Kittatinny Supergroup. Miller and Myers extended the formation into Pennsylvania in 1939,Miller, B.L., and Myers, P.B., 1939, Hardyston formation, IN Miller, B.L., and others, Northampton County, Pennsylvania: Pennsylvania Geological Survey County Report, 4th series, no. 48, p. 206-223.

Milk River at Writing-On-Stone Provincial Park The Foremost Formation is the basal unit of the Belly River Group (called the Judith River Group in the United States). It gradationally overlies the marine shales of the Pakowki Formation. It consists of sediments that were eroded from the mountains to the west and carried northeastward by river systems, where they gradually prograded into the Western Interior Seaway.Eberth, D.A. 2005.

The La Loche Formation is the basal unit of the Elk Point Group and rests unconformably on the eroded Canadian Shield. It is gradationally overlain by the Contact Rapids Formation in the Clearwater River area, and by the Chinchaga or the Keg River Formation in the Slave River area north of Lake Athabasca. It may be considered equivalent to the Contact Rapids or Chinchaga Formation in some areas, and may also be referred to as the Basal red beds or the Granite Wash.

Learning to play football with local club Chorrillo at a very young age, la Guardia gradationally advanced from the team's youth categories to their reserve and senior teams by age 16. Given the opportunity to participate in an A.C. Milan-hosted youth football camp at Santa Clara beach, Panama, the midfielder impressed the coaches there but never made the trip to Italy. At the end of 2010 the Panamanian returned to youth football, joining the La Academia de Saladas in Argentina.

The Gai-As Formation gradationally overlies the lacustrine deposits of the Huab Formation in the western part of the basin, but in the east succeeds the fluvial deposits of the Huab Formation with a sharp contact. The basal beds of the formation are ubiquitously represented by fine-grained distal deposits and imply a much larger extent of the formation due to the absence of sediments from marginal environments.Horsthemke et al, 1990, p.73 The lower part of the succession is formed by approximately of thick reddish-violet, slightly calcareous shales.
