Black granites

Black Granites provides the hardness and strength of granitic rocks. These granites, otherwise called disbases, are primarily gabbro or dolerite rocks. Further, black granites are mainly of volcanic origin and remain in the form of dykes. The grains in black granites are fine to medium-sized and of black colored. Dolerites are 49.5% of Felspar, 35.2% of Pyroxene, and 8.3% of Iron Ore, which has a bit different composition than granites where Felspar is 54%.

If we consider the physical properties of black granite, then these have high compressive strength, tensile strength, and shear strength of about 1500-3500kg/cm2, 150-350 kg/cm2, and 250-600 kg/cm2 respectively. Further, these have a high density as compared to its pink and grey variety. Black Granites are the commercial granites mainly found in Chittoor district of Madhya Pradesh, Surutapalli, Prakasam District, and Warangal District of Hyderabad, Large deposits of dolerite or black granites are also seen in Assam, Tamilnadu, Karnataka, Rajasthan, West Bengal, Bihar, Kerala, Odisha, and Maharashtra.

The basic dykes of these granites have exceptional patterns of cross-cutting, ramifying, and fusing systems. Basic dykes have a range of 3.5 to 100 m. in width along with definite texture. Attractive interior and exterior designs, including countertops, cladding, floors, and other elegant structures, looks excellent with black granites.

Black Granites provides a wide range of styles and types, which gives an astonishing finish. Further, these are easy to maintain and manufactured at an affordable price and, thus, famous world-wide.
