Aug 13, 2019 · 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.
Sandstones are clastic sedimentary rocks that are composed largely of sand-sized grains (>50% particles between 1/16 and 2 mm diameter). Sandstones make up approximately 14% of sedimentary rocks and can be found in a wide variety of depositional environments including alluvial fans, rivers and floodplains, beaches, and submarine fans.

What is Sandstone? Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains.
Sandstone is a sedimentary rock composed mainly of sand -size mineral or rock grains. Most sandstone is composed of quartz and/or feldspar, because these are the most common minerals in the Earth 's crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray, and white. 1. 2. 3. 6. 8.
Sandstone. On the Web. On Wikipedia. Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains.
