Calcite is a mineral and limestone is a sedimentary rock that contains calcite.imestone usually is composed of finer grained material of calcite origin, such as sea shells, or precipitates of calcite origin. Limestone will effervesce in slightly acidic solutions such as vinegar because of the chemical reaction of calcium carbonate with acid.
Limestone means any rock formed mostly of calcium carbonate (CaCO3), but to geologists, limestone is only one of several types of carbonate rocks.. These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO3) or dolomite (calcium-magnesium carbonate, CaMg[CO3]2) or both.
