Webarenite, 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. Weblithic arenite, sandstone ( i.e., sedimentary rock composed of grains 0.06–2 mm [0.0024–0.08 inch] in diameter) containing over 50 percent rock fragments.
