Summarize the formation of sandstone
Formation of the sandstones are cemented grains that mayeither be fragments of a pre-existing rock or be mono-minerallic crystals. Thecements binding these grains together are typically calcite, clays, and silica.Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to2 mm (0.0025–0.08 … See more Chemical Composition of sandstone usually quartz framework grains are the dominant mineral in clastic sedimentary rocks.
