Red sandstone composition
WebA quartz arenite or quartzarenite is a sandstone composed of greater than 90% detrital quartz. [1] Quartz arenites are the most mature sedimentary rocks possible, and are often referred to as ultra- or super-mature, and are usually cemented by silica. They often exhibit both textural and compositional maturity.
