The environment is thought to have been on the foreshore or a shoaling part of the shelf (Noad, 1998). Sandstone and mudstone interbeds. This is a very heterolithic facies. It is a set of interbedded very fine-grained sandstone, siltstone and mudstone. The sandstone beds are less than 150 cm and are packed with carbonaceous material. Rippling ...A study of the Brent Group sandstones, in well 211/13-A33 in the Thistle Field, northern North Sea, UK, from a sequence of shoreface, foreshore, delta plain and finally barrier shoreline depositional environments, was undertaken with the aim of contrasting the roles of depositional and diagenetic processes on reservoir quality.It suggests that the source sediment traveled a great distance before stopping in its depositional environment and forming the sandstone. Sandstone's texture and density can also vary, and ...Pyrite is a common accessory mineral in sedimentary rocks, particularly in limestone, sandstone and carbonaceous siltstones or shales. Some times we wonder who and why it got there; and what does it mean for petroleum exploration. ... formed in the depositional environment, or early diagenetic, formed during the transformation of the sediment ...The Aptian-Albian Bima Sandstone non-conformably overlies the Precambrian basement rock and the sandstone is the oldest Cretaceous succession in the Upper Benue Trough.

To give one example, by reconstructing depositional environments of certain sediments deposited along the coast of the Pacific Northwest, geologists concluded that great subduction earthquakes and tsunamis (giant waves) created by the earthquakes, were the driving forces of the depositional environment of those sedimentary deposits. This has ...
