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 very common sedimentary rock consisting of calcium carbonate (more than 50%). Limestone is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).
