Where does quartz sandstone form

Greywacke. Greywacke is variation of sandston

2.1.4.1 Material Composition. The matrix materials in the deformable porous media are made up of either one single mineral or several minerals. For example, quartz sandstones are mainly composed of quartz (SiO2), while greywacke is composed of quartz, feldspar, mica, clay, and other minerals. Sandstone is composed of sand-sized (0.0625…2 mm) mineral grains, rock fragments, or pieces of fossils which are held together by a mineral cement. It grades into siltstone, shale or mudstone (grains less than 0.0625 mm in diameter) and conglomerate (or breccia if the clasts are angular) if the average grain-size exceeds 2 mm 1.

Sedimentary rocks are formed by the deposition and subsequent cementation of materials on Earth’s surface and within bodies of water. Examples of sedimentary rocks include chalk, limestone, shale, quartz- lithic sandstone, conglomerate, chert, carbonaceous mudstone, and coal seams.Sandstone is a type of rock made primarily of minerals derived from sand. The stone is formed over hundreds of years by lakes, rivers, and ocean floor deposits. These elements compress when they contact quartz or calcite. The pressure of these minerals coming together over time forms sandstone.A metamorphic rock used to be some other type of rock, but it was changed inside the Earth to become a new type of rock. The word metamorphism comes from ancient Greek words for “change” (meta) and “form” (morph).
