Sedimentary Rock Identification Physical Geology

Sedimentary Rock Identification. Introduction. Rocks are made of minerals. Rocks can be a mixture of different kinds of minerals, a mixture of many grains of the same kind of mineral, or a mixture of different grains of rocks.

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.
