Sandstone Wikipedia
Sandstone is a clastic sedimentary rock composed mainly of sandsized (0.0625 to 2 mm) mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar (both silies) because they are the most resistant minerals to weathering processes at the Earth''s surface, as seen in the Goldich dissolution series.
