Quartz sandstone sedimentary rock

For example, quartz veins are often found in association with gold and sulfide minerals in hydrothermal systems, and quartz can also be found in sedimentary rocks that are formed in arid or semi-arid environments, such as sandstone and chert. In igneous rocks, quartz can be found as phenocrysts in volcanic rocks, or as a major ….

Sandstone is a clastic sedimentary rock comprised of sand-sized particles about .1 to .2 mm in size. It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. The sand grains are most often made of quartz, cemented together by calcite or silica.
