Limestone is mainly formed in a shallow sea environment. Limestone generally contains some dolomite and clay minerals. When the content of clay minerals reaches 25% to 50%, it is called argillaceous rock. When the dolomite content reaches 25%~50%, it is called dolomitic limestone. Limestone is widely distributed, uniform in lithology, easy to be mi...
