e. Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues. This process is a fundamental aspect of the life cycle ...
Aragonite is a carbonate mineral and one of the three most common naturally occurring crystal forms of calcium carbonate (Ca CO 3), the others being calcite and vaterite. It is formed by biological and physical processes, including precipitation from marine and freshwater environments. Aragonite crystal structure.
A carbonate is a salt of carbonic acid, H2CO3, [ 2 ] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2−3. The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate groupO=C (−O−)2.
Category. : Carbonates. Wikimedia Commons has media related to Carbonates. Carbonates are salts, esters, and natural minerals with the carbonate anion (CO 32−). They tend to be of a basic pH.
The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. [ 1 ] In other words, it is a biologically mediated process which results in the sequestering of carbon in the deep ...
Biomineralization: Complete conversion of organic substances to inorganic derivatives by living organisms, especially micro-organisms. [1] Fossil skeletal parts from extinct belemnite cephalopods of the Jurassic – these contain mineralized calcite and aragonite. Biomineralization, also written biomineralisation, is the process by which living ...
Carbonate minerals are those minerals containing the carbonate ion: CO 3. Subcategories. This category has the following 3 subcategories, out of 3 total. A. Alabaster ...
The geochemistry of carbon is the study of the transformations involving the element carbon within the systems of the Earth. To a large extent this study is organic geochemistry, but it also includes the very important carbon dioxide. Carbon is transformed by life, and moves between the major phases of the Earth, including the water bodies ...
