Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth. Shales are often found with layers of sandstone or.Sandstones are named on (1) the abundance of muddy matrix and (2) the composition of the sand grains. Matrix: arenites vs. wackes. Sandstones can have matrix (silt and mud-sized particles) between the sand-sized grains, or can have cement (precipitated mineral, mostly calcite or quartz) between the grains. When Schist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary rocks, such as shales and mudstones, have been subjected to compressive forces, heat, and chemical activity.Description Diagram showing deposition of sand that would become Berea Sandstone.

To evaluate this property, a scale of textural maturity that involved four textural stages was devised in 1951. These stages are described as follows.

Sandstone is a sedimentary rock formed from cemented sand-sized clasts. The cement that binds the clasts can vary from clay minerals to calcite, silica or iron oxides.
