* Limestone: Limestone is a sedimentary rock that is composed mostly of calcium carbonate. It is formed from the accumulation and compaction of the shells and skeletons of marine organisms, such as corals, mollusks, and algae.
* Dolomite: Dolomite is a sedimentary rock that is composed mostly of calcium magnesium carbonate. It is formed from the alteration of limestone by the action of magnesium-rich fluids.
* Chert: Chert is a sedimentary rock that is composed mostly of microcrystalline quartz. It is formed from the precipitation of silica from groundwater or surface water. Chert can contain the remains of marine organisms, such as radiolarians and diatoms.
* Coal: Coal is a sedimentary rock that is formed from the accumulation and compaction of plant material. Coal is a valuable source of energy and is used to generate electricity and power industrial machinery.
* Oil shale: Oil shale is a sedimentary rock that contains a high concentration of organic matter. Oil shale can be processed to extract oil, which can be used to make gasoline, diesel fuel, and other petroleum products.
