A quartz arenite or quartzarenite is a sandstone composed of greater than 90% detrital quartz.Blatt, Harvey and Robert J. Tracy, Petrology: Igneous, Sedimentary, and Metamorphic, Freeman 2nd ed., 1996, p. 518 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.Prothero, D. R. and Schwab, F., 1996, Sedimentary Geology, pg. 96-98,
