Sedimentary Rocks University of Pittsburgh

Coal is made of compressed plant debris and thus is a biochemical rock. However, since coal is often found interlayered with clastic rocks, we'll discuss coal with the clastic rocks. Carbonate rocks include limestone, which is made of calcite (CaCO 3), and dolostone, which is made of dolomite (CaMg(CO 3) 2). Dolomite often forms when limestone
