Web16 mrt. 2015 · The sandstone can be classified according to the Folk's classification. If a sandstone has above 90% quartz so it will be quartz arenite. If it has more feldspar it will be arkose and will increasing lithics and feldspar, changes from arkose to lithic arkose and then to feldspathic litharenite. Same is the case with quartz and lithic fragments. Lithic sandstones, or lithic arenites, or litharenites, are sandstones with a significant (>5%) component of lithic fragments, though quartz and feldspar are usually present as well, along with some clayey matrix. Lithic sandstones can have a speckled (salt and pepper) or gray color, and are usually associated with one specific type of lithic fragment (i.e., igneous, sedimentary, or metamorphic).
