To view the original source information, use the "Learn more" links.Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, [1] chunks, and smaller grains of rock broken off other rocks by physical weathering. [2]en.wikipedia.org/wiki/Clastic_rockClastic rocks are rocks which are composed of small fragments of other rocks. These fragments, known as clasts, determine the composition and texture of the clastic rock. One well-known example of clastic rock is sandstone, a type of rock made from sand-sized fragments of other rocks.www.allthescience.org/what-are-clastic-rocks.htmClastic rocks are the broken bits and pieces of older rocks that lithified (turn to stone) and became new rocks. The broken bits and pieces of older rocks are clasts. Clasts can be as tiny as the dust on the sill of a window or large boulders.www.kids-fun-science.com/clastic-rocks.htmlA clast is a fragment of rock or mineral, ranging in size from less than a micron (a millionth of a meter) to as big as an apartment block. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock.open.maricopa.edu/physicalgeologymaricopa/chap…- See more
