arenite

any sedimentary rock that consists of sand-sized particles (0.06-2 millimetres [0.0024-0.08 inch] in diameter), irrespective of composition. More formal nomenclature of such rocks is based on composition, particle size, and mode of origin-e.g., sandstone, quartzite, lithic arenite, and feldspathic arenite.
