The beginning of diamond Discovery

The beginning of diamond Discovery

At first diamond was discovered in meteorites by Erofeev and Lachinov in 1888. It was assumed highly exact origin of these diamonds in meteorites. Some scientists believe that diamonds form because of the high pressure deep in the planetary bodies (Orlov, 1977). Another hypothesis suggested that the popular diamond-shaped impact with the ground, that would provide materials to a high pressure (Orlov, 1977). However, the extent of diamonds in extraterrestrial rocks is one minute. Diamond mining on a large scale, we must look at our planet.

Terrestrial volcanic rocks

The occurrence of major geological of diamonds in kimberlites found in the upper sections of the Earth's crust. According to Orlov (1977), "was found on the first urgent bearing kimberlites in Kimberley South Africa and De Beers" (p. 160). Kimberlites Join exist only in the middle of a stable tectonic continents known as shields or platforms. They also occur pipes, dams, and veins, and thresholds consist of alkaline volcanic rocks rich. Researchers believe that can be attributed to such intrusions of magma alkalitic of upper mantle paid in systems is a big mistake to the upper areas of the earth's crust (Orlov, 1977).

Studies have shown that kimberlite pipes (Figure 2) occurs more easily near the marginal areas of the earth's crust with bows. This shows the deep divide systems with intense pressure from the previous upwelling of magma. And usually suppress kimberlite pipes form known to contain high levels of xenoliths of sedimentary rocks. This causes popular during the invasion of the upper part of the deep when he sits platform happens rocks along the way of the rising magma. Times dominant volcanoes diamond-bearing kimberlite signed during the Precambrian and early Paleozoic (Orlov, 1977).
