Everything You Need to Know About Sandstone

2019-8-13 · Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.Sedimentary Rocks and the Rock Cycle2020-8-26 · Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates.
