Everything You Need to Know About Sandstone

 · 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.

Sandstone sedimentology and stratigraphyAAPG Wiki

 · Sandstone is a clastic sedimentary reservoir rock composed of mainly quartz and/or feldspars and typically deposited by relatively high-energy processes which winnow out much of the fine particle size fraction while transporting and depositing the coarser (sand-sized) particles. Like sand sandstone may be any color but the most common colors are tan brown yellow red grey pink white
