Clastic rock Wikipedia
Clastic rocks are composed of fragments or clasts of preexisting minerals and rock A clast is a fragment of geological detritus chunks and smaller grains of rock broken off other rocks by physical weathering Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load and in sediment deposits

6 1 Clastic Sedimentary Rocks – Physical Geology
6 1 Clastic Sedimentary Rocks 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 5 12 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
Igneous Rocks
Sedimentary rocks form by breaking down other kinds of rocks into small particles and washing or blowing them away metamorphic rocks form from other rocks and igneous rocks form by melting other rocks Thus rocks are always changing form and are redistributted as part of a giant cycle of renewal This cycle is called the Rock Cycle
