The limestone is also called calcite, this is wrong, the naming principles of rock is more stringent, is the crystallization of calcite rocks, although the ingredients are calcium carbonate, but mixed together with limestone. Not like quartz crystal and the same reason.
That is the most simple, limestone is calcium carbonate sediments of shallow marine bathyal deposits, limestone can find aeschnidae fossils, and the marble is late due to low temperature hydrothermal alteration of metamorphic rocks, its formation mechanism is very complex, the time span is very long, metamorphic depth, in different regions are not the same.
Limestone is used as the raw material of lime, cement, nylon and so on;Marble is mainly used as building materialAs for other minerals in the rocks are associated with or derived from the latter is generally due to crustal movement
