Oolitic Aragonite- Ocean’s calcium carbonate

Oolitic aragonite is the purest form of calcium carbonate precipitated in the oceans naturally. It has its orthorhombic and bipyramidal crystalline structure. The needle shape in their structure gives more practical advantages. These oolitic aragonite sands are formed by the carbon dioxide present in them. The carbon dioxide formed from the photosynthesis combines with green algae which are available in waters. The precipitate caco3 will be formed at the rate of 4 billion per year in the banks of Bahamas. Oolitic aragonite is composed of calcite or aragonite. Also aragonites can be phosphate, clays or irons. These oolites are mainly found in warm, supersaturated marine water areas. They are mainly used in home aquarium industry. Because of its extremely small in size and bigger surface area they promote higher bacterial growth. Based on property of bacterial growth they are used in agricultural field to increase the crops growth.

How oolitic aragonites are formed? Whitings  is the process which exist behind the formation of oolitic aragonite. Whiting is the phenomenon of calcium carbonate precipitation created with the help of photosynthesis process. Fishes in the waters disturbes the water bottom and gets the sandy structures move to the upper waters. Picoplankton predominately called as the cyanobacteria seasonally enters the water. After photosynthesis and calcification process it combines with the carbon dioxide present in the environment. It makes our environment clean as it eliminates the carbon dioxide during its creation.

How carbons are taken during aragonite creation?

Mineralisation of carbon dioxide to calcium carbonate with the help of phytoplanktons is the process besides the oolitic aragonite formation. The phytoplanktons may be picoplankton or any green algae. Photosynthesis acts as the major process to obtain both forms of carbon sequestration by cyanobacteria. Initially Co2 is reduced to organic compounds at the time of oxygen production through the Calvin-Benson-Bassham cycle.  After that it mineralises Co2 to calcium carbonate.
