Volcanic-rock …Sandstone is made of sand grains (0.05mm to 2mm) that may have been deposited in the sea, by rivers, or in deserts, and later cemented together by minerals precipitated from groundwater. Most sandstones are made up largely of quartz grains, because quartz is a very hard and chemically-resistant mineral. How does sandstone …Sandstone is a sedimentary rock formed due to the breakdown and weathering of other rocks. As its name suggests, sandstone is formed underground from grains of sand that have been cemented and compacted by the pressure of rock formations lying above them. Using a magnifying glass, you can see the individual grains of sand that make up the rock.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. When there is a significant amount of clay or silt, geologists refer to the rock as argillaceous sandstone.

Intermediate rocks that mix sand and clay—mudstones—metamorphose into schists or gneisses. The sedimentary rock limestone recrystallizes and becomes marble. Igneous rocks give rise to a different set of minerals and metamorphic rock types.It is dominated by quartz, and in many cases, the original quartz grains of the sandstone are welded together with additional silica.
