Carbonate Rock Formation Limestone dolomite or dolostone and marble are often collectively referred to as carbonate rocks because the main mineral is calcite The chemical name of calcite is calcium carbonate Limestone dolomite sandstone and shale are sedimentary rocks there are also other sedimentary rocks that are often found

Chinese carbonate rock commonly has relatively low organic abundance mostly less than 02 and high organic maturity which is different from the carbonate rock in other parts of the world Whether Chinese carbonate rock can serve as a source rock has long been a topic of debate

Calcium carbonate is the main ingredient of limestone rocks chalk and marble Although all three forms have similar chemical composition they differ in thickness hardness and whiteness Carbonate rocks are subject to very small changes but are highly soluble in water which contains carbon dioxide

Most carbonate deposition also requires relatively warm waters which also enhance the abundance of carbonate secreting organisms and decrease the solubility of calcium carbonate in seawater Nevertheless carbonate rocks form in the deep ocean basins and in colder environments if other conditions are right
