How sedimentary rocks are classified
Detrital sedimentary rocks are mainly classified by the size of their grain. The largest grain is a boulder, followed by a cobble, a pebble, sand, silt and finally the finest grain, which is clay.Oct 2, 2019 · CLASTIC. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported by erosion to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
