Sandstone

Sandstones are a type of clastic (terrigenous) sedimentary rocks deriving, as the name suggest, from the consolidation of sandy sediments. Sand consists of clastic particles produced by the erosion of pre-existing rocks with grain size comprised between 0.0625 and 2 mm. The upper boundary of 2 mm arbitrarily separates sand (and sandstones) from the coarser gravel and …
