Description

A coarse-grain feldspathic sandstone. Arkose is composed of quartz, feldspar, calcite, and mica and is produced from the disintegration of granite. It is an important type of sediment as it tends to contain a significant number of fossils. In Australia, the world's largest natural monolith, Ayers Rock, is formed by massive deposits of arkose. Arkosic sandstone is used as a dimension stone in building construction.
