Limestone Facts

Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3) Because sedimentary rocks are made of various types of sediments the other 50% of a limestone rock could be virtually any other mineral Limestone originates in wet areas which mean it could also be composed of shells and waste matter from organisms Get price
