Sandstone is composed of sand-sized (0.0625…2 mm) mineral grains, rock fragments, or pieces of fossils which are held together by a mineral cement. It grades into siltstone, shale or mudstone (grains less than 0.0625 mm in diameter) and conglomerate (or breccia if the clasts are angular) if the average grain-size exceeds 2 mm 1.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.

Clastic sedimentary rocks – such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks – such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved minerals precipitate from solution.Real Sandstone Facts::black_circle: Sandstone is a clastic sedimentary rockcomposed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments.:black_circle: Its Composition is typically quartz and feldspar; lithic fragments are also common.
