Several types of black granite

Basalt is one of the important rock types in black granite. The color is mostly black or gray-black, and it is fine-grained and dense. Its compressive strength is about 35005000kg\/cm2, and it has strong acid resistance, abrasion resistance, compression resistance and insulation properties. Basalt is widely distributed in my country, and it has been produced in almost every geological period.

Gabbro is also an important rock type of black granite, the color is mostly black, the color is pure. Partial black background is decorated with white dots, and the stone types are forest green (Hebei, Henan). The rock species are mainly Greenstone. However, from the perspective of commercial properties, they are all named after granite. Basalt is extrusive rock with darker color. The mineral particles contained are average and small, and it is difficult to distinguish the natural stone type with the ordinary naked eye, even using a magnifying glass. It is also not easy to distinguish.

Dolerite, a shallow facies rock of basic intrusive rock, is also an important rock type of black granite in my country. Comparable or even superior to them. According to research, the main rock type of Shanxi black is diabase, the so-called Shanxi black A. In China, the good quality black granite is Shanxi black A grade, and the price is higher than any Indian produced. The black granites are all high. Shanxi Hei A contains the following practical mineral components: about 50% plagioclase, with polymorphic twins developed; ordinary-volatile pyroxene about 35%; a small amount of mid-feldspar, about 5% A small amount of minerals include amphibole, biotite, titanomagnetite, etc.
