What rock is an example of a chemical sedimentary rock?
Web16 apr. 2024 · Biochemical sedimentary rocks are formed from shells and bodies of underwater organisms. The living organisms extract chemical components from the water and use them to build shells and other body parts. The components include aragonite, a mineral similar to and commonly replaced by calcite, and silica. WebMost sedimentary rocks, including rocks of Precambrian age, contain at least a small amount of organic matter consisting of the preserved residue of plant or animal tissue. The average content of organic matter in sedimentary rocks is about 2.1 weight percent in mudrocks, 0.29 percent in limestones, and 0.05 percent in sandstones (Degens, 1965). Web25 feb. 2024 · Sedimentary rocks from the different age rock complexes in the European Lowlands (specifically, the Polish Lowlands) have for years been the focus of studies aiming to identify their prospects for the occurrence of mineral and/or non-mineral deposits.
