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, however, is very rarely pure calcite, pure dolomite, or a pure mixture of the two. It typically contains a variety of accessory rock materials of which quartz, chert, clay and pyrite are among the noteworthy.oth are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O). Each carbon atom is combined with three oxygen atoms to form what is called carbonate (formula CO3).
