Sandstone - Wikipedia
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks.

Sandstone: Sedimentary Rock - Pictures, Definition & More
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.

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.

Description. Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.

Series: Geology. sandstone. Sandstone is made of tiny pieces of sand you can see and feel. You can actually scratch away grains of sand from a piece of sandstone. It forms when wind, ice, and water carry away grains of sand and drop them someplace new—usually at the bottom and along sides of rivers, lakes, and coastlines.
