Quartz sandstone
Quartz sandstone results from the extreme weathering and sorting of a sediment until everything that can be removed has been removed. Complete chemical weathering is required to remove all feldspars and lithics, but the final removal of the clay takes place in high energy environments, typically beach environments, although other …

Sandstone
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. The color of sandstone varies, depending on its composition.
