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 is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO 3). Limestone constitutes approximately 10 percent of the sedimentary rocks exposed on the earthâs surface.ith more time and pressure, a coarsely crystallized rock can form, which is limestone.
