FORMATION OF NOBLE AND NON-FERROUS METAL DEPOSITS IN VARIOUS REGIONS OF THE EARTH (ON THE EXAMPLE OF MINOR CAUCASUS)

Abstract

The infiltration of ocean water through the volcanic basaltic layer leads to the formation of the 3rd serpentinized layer of the oceanic crust. Due to tectonic processes, relicts of oceanic crust were preserved at various depths of the continental crust in different regions of the Earth. Due to the increase in pressure and temperature, the serpentinized rocks of relicts dehydrate, which leads to the release of hydrogen, hydrocarbons, geofluids, etc. The products formed in the deep crust (hydrocarbons, geofluids, etc.) migrate through deep faults to the upper horizons of the crust, involving noble and colored elements and their various compounds. It is a known fact that deposits of noble and non-ferrous deposits are of geothermal origin and are located mainly within deep faults. Therefore, it is expedient to carry out the exploration and investigation of those deposits in the range of deep faults.
