description of calcite

Geology

Limestone. Limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite - CaCO 3 ). There are many different types of limestone formed through a variety of processes. Limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral
