Arenite
Definition
A clastic or detrital sedimentary rock composed of medium-grained mineral particles, with diameters structurally ranging from 0.0625 to 2 millimeters (sand-sized particles), cemented within a fine matrix. Unlike wacke, an arenite contains less than 15% interstitial clay matrix, being strictly classified based on grain composition into quartz, feldspathic, or lithic arenite.
