The types of rock: igneous, metarmorphic and sedimentary

clastic sedimentary rocks; basically small rock fragments (many silicates) transported and deposited by fluids (water, bed flows). These rocks are further classified on the size and composition of the clastic crystals included in the sedimentary rocks (most often quartz, feldspar, mica and clay).

A feldspar-rich sandstone is called an arkose. Lithic rich sandstones are called litharenites. Further subdivisions are shown in the diagram. If the rock has between 10 and 50% clay matrix, the rock is called a wacke. Quartz wackes have predominantly quartz surrounded by a mud or clay matrix.
