india absolute black granite tile countertopsGranite is an intrusive rock in acidic magmatic rocks, which is the most common type of rock in this category, mostly light red, light gray, grayish white and so on. Medium coarse grain, fine grain structure, block structure. Some are also patchy structures, globular structures, and plaque-like structures. The main minerals are quartz, potassium feldspar and acid plagioclase, and the minor minerals are biotite, hornblende, and sometimes a small amount of pyroxene. There are many kinds of secondary minerals, such as magnetite, vermiculite, zircon, apatite, tourmaline, fluorite and the like. The quartz content is the most among various magmatic rocks, and its content can range from 20-50%, and a few can reach 50-60%. The content of potassium feldspar is generally more than that of plagioclase. The ratio of the content of the two is often two-thirds of the total feldspar of potassium feldspar, one third of feldspar, and more potassium feldspar in granite. It is light red and gray, gray and gray. Gray-white potassium feldspar and plagioclase are often difficult to distinguish on hand specimens. At this time, we must carefully observe the twin crystal characteristics of these two feldspars, because the plagioclase has a polycrystalline twin crystal, and when the hand specimen is rotated, there are regular bright and dark patches on the plagioclase crystal, and potassium feldspar. It is a card type twin crystal, which is expressed as two crystals with different brightness.

Granite tile countertop has high density, high hardness and wear surface. It is also one of the materials frequently used in home decoration. Compared with natural marble, granite countertops has better antibacterial regeneration ability in materials that can be used in kitchen countertops.
