Calcite is a kind of calcium carbonate mineral, which is the most common natural calcium carbonate . Therefore, calcite is a kind of widespread mineral. Calcite crystal shape varied, their aggregate can be clusters of crystals, can also be a granular, block, fibrous, stalactite, soil and so on. Rap calcite can get a lot of square pieces, therefore calcite. Calcite is divided into natural and small square solution, and state of ice and rock.

Granite is a common type of felsic intrusive igneous rock which is granular and phantomatic in texture.,mainly consisting of feldspar, quartz. The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock. its SiO2 content usually lies above 7o%.Granites can be predominantly white, pink, or gray in color. These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals. By definition, granite is an igneous rock with at least 20% quartz and up to 65% alkali feldspar by volume.
