WebDolomite (also known as "dolostone" and "dolomite rock") is a chemical sedimentary rock that is very similar to limestone. It is thought to form when limestone or lime mud is modified by magnesium-rich ground water. The specimen shown above is about four inches (ten centimeters) across. WebDolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg (CO 3) 2.

Marine biogenic calcification - Wikipedia

WebMost detrital limestones are made of biogenic grains rather than weathered bits and pieces of preexisting rocks. Calcium carbonate in the form of aragonite and calcite are extremely common biominerals. They are used to build tests, shells, exoskeletons, etc. of millions of marine (mostly) species. WebMarine biogenic calcification is the process by which marine organisms such as oysters and clams form calcium carbonate. Seawater is full of dissolved compounds, ions and nutrients that organisms can use for energy and, in the case of calcification, to build shells and outer structures.

WebDolomite (CaMg (CO 3) 2) is another carbonate mineral, but dolomite is also the name for a rock composed of the mineral dolomite (although some geologists use the term dolostone to avoid confusion). Dolomite rock is quite common (there’s a whole Italian mountain range named after it), which is surprising since marine organisms don’t make dolomite. WebFormed by chemical precipitation from a concentrated solution in water as salt, gypsum, or limestone. Characteristics: Soft, because they are composed of soft minerals such as halite, gypsum, calcite. They can easily be scratched with steel or a copper penny. Commonly fine‑grained and homogeneous. Fossils are common in limestone.
