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]

Apr 24, 2024 · A clast is a fragment of rock or mineral, ranging in size from less than a micron [1] (too small to see) to as big as an apartment block. Various types of clasts are shown in Figure 6.1.1 6.1. 1 and in Exercise 5.3. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock.
