==Lithic arenite provenance==

Lithic arenite consists of a fairly high content of unstable rock fragments such as volcanic rocks and metamorphic rocks clastics. Lithic arenite fragments can be composed of [[chert]]. These sandstones may contain less than 90 percent of quartz grain and assemblage of rock fragments are more unstable than feldspar. The color is usually light gray and dark gray. Most lithic arenite are poorly sorted. Most of lithic arenite have an immature to submature textural maturity. Lithic arenite may appear on marine turbidite sediments and fluvial. Pettijohn (1963) estimates that the lithic arenite and graywacke make up nearly half of the sandstones. The lithic fragments indicates the source of sediments derived from high relief environment. These sandstones are usually present on the [[alluvial]] fan but can also be present in the fold thrust belt in the Foreland basin. Volcaniclastic sandstone is a special kind of lithic arenite derived from volcanic detritus. Usually formed of pyroclastic material that transported or reworked. Typically characterized by the presence of euhedral feldspar, pumice fragments, glass shards, fragments of volcanic rocks, and little quartz content.
