5.5: Classification of Sedimentary Rocks
Crystalline Limestone. Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ( CaCO3) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 ). About 10% of sedimentary rocks are limestones.
