Solid calcite reacts with hydrochloric acid by effervescing or fizzing. There are some microscopic marine and freshwater organisms that make their shells of silica. Chemical sedimentary rocks can be subdivided into groups of BIOCHEMICAL ORIGIN and INORGANIC PRECIPITATES. Organic. There are also a few brachiopod shells in this nice sample. Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces.The fossils in these rocks may be of macroscopic or microscopic size. These are normally shell and skeletal fossils of the organisms that produced the limestone. Limestone is mostly made of calcite (CaCO 3) and sometimes includes dolomite (CaMgCO 3), a close relative.
