Quartz arenite

A 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. The two primary sedimentary depositional environments that produce quartz arenites are beaches/upper shoreface and aeolian processes.^[2]

Quartz arenite makes up the Prospect Mountain Quartzite on top of Doso Doyabi, Nevada
