Sedimentary rock is composed of framework grains, matrix, chemically precipitated cement, and pores (Fig. ). Framework grains and matrix are generally deposited from a fluid medium after transport. Transport distances may be thousands of kilometers or only a few meters. The grains, as the name indicates, form the framework of the rock.
