Sandstone

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments.. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth''s surface, as seen in Bowen''s reaction series.Like uncemented sand, sandstone may be any color due to impurities within the ...

grinding identification of rock by other particles

Abrasion happens when rock or sand wears down larger pieces of rock. Abrasion happens in areas where there are strong winds, loose sand, and soft rocks.
