Macerals are to coal as sediment grains and cements are to sedimentary rocks. Coal petrographers (people who study coal under a microscope) separate macerals into three groups, each of which includes several maceral types. The groups are inertinite, liptinite, and vitrinite.

Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the "Earth's Minerals" chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure 5.

Jul 28, 2011· Sedimentary rocks are easy to identify because of the visible layers. Most sedimentary rocks form under the water (sea). Sedimentary rocks normally have pores since they form from sediments. Shale, sandstone, limestone, conglomerate, and coal are some examples of sedimentary rocks. These rocks are usually rich in fossils.
