Sandstone. Sandstones are a type of clastic (terrigenous) sedimentary rocks deriving, as the name suggest, from the consolidation of sandy sediments.

Sandstone is a clastic sedimentary rock composed of mostly sand-based minerals. This stone is the second most abundant sedimentary rock on the earth’s surface. It can be split into three specific categories depending on the grains that make up the majority of the stone: quartz, feldspar, or lithic.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.
