WebThe sand grains are, however, still poorly sorted in these rocks. Submature sandstones are common as river-channel sands, tidal-channel sands, and shallow submarine sands swept by unidirectional currents. Mature sandstones are clay-free, and the sand grains are subangular, but they are well sorted--that is, of nearly uniform particle size. WebSandstone can be classified based on composition (e.g. quartz arenite, arkose, lithic sandstone) and texture (e.g. well-sorted, poorly sorted, conglomeratic). Sandstone is …
