Researchers at the University of Wits in Johannesburg, South Africa, have found the answer to the enigma that geologists have been facing for years.


The question is how certain magical rocks, which are formed by the crystallization of the magical chambers in the Earth's crust, break the norm and contain minerals in random proportions.

Usually, magic rocks consist of some fixed proportions of different minerals. For example, geologists know that a certain rock will have 90% of one mineral and 10% of another mineral.

However, there are some magic stones that obey this norm and do not follow this general rule. These rocks, called non-contact rocks, contain minerals in completely random proportions.

One example is chromite anorthosis from the famous Bushwood complex in South Africa. These rocks contain 15% to 20% of chromite, instead of only 1%, as was commonly expected.

"Traditionally, these rocks with this incorrect composition have been classified as mechanically mineralized by one magma highway or by mechanical mixing of minerals from two or more different spheres," said Professor Rice Latipov of the School of Science.

Both have seen serious problems with this approach, with Latifov and his colleague Dr. Sophia Chistyakova, as well as the Wits School of Geoscologies, finding that there is in fact a simple explanation for the question – and it has nothing to do with mechanical sorting or mixing. Minerals produce these rocks.

Their research, which was published in the journal Geology, Shows that an excess amount of some of the minerals in these rocks can be generated in the supplier conductors, along which the solid travels from the deep deployment chambers to the earth’s surface.

“While traveling through the provider's channels, Magma comes in contact with cold sidewalks and begins to crystallize.

The general principle of this approach can be applied to the Earth’s plutonic and volcanic environment with any magnetic rocks with incorrect proportions of minerals.

"It is possible that the search for the existence of other petrological problems of magnetic complexes should not be sought in supply conductors than in the magma chambers themselves. This attractive approach holds great promise from countless petrologists working with basalt magma complexes." – says Latipov.
