DENSITYREGULARITIES OF COLORED AND NOBLE METALS IN THE BORDERS OF THE MALKIN ULTRABASIC MASSIVE (KABARDINO-BALKAR REPUBLIC)

Abstract

The paper substantiates a new approach to the purposive ore mineralization forecast of the Malkin ultrabasic massif based on analysis and special processing of modern chemical analytical data, using petrological modeling methods and comparative petrochemical analysis of reference objects, as well as creating graphical spatial models based on GIS processing and reinterpretation of existing geological and geophysical data. It is established that the distribution in space of various minerals is determined by the location of ultrabasic rocks, and their manifestation in time is associated with the steps and stages of magmatic formation and epigenetic changes in ultrabasic rocks of the Malkinmassif. It is shown that iron and cobalt-nickel ores are confined to ferruginous apogartzburgites, and chromite ores are selectively localized in dunites. This makes it possible to predict the most valuable minerals in the part of the mass that is covered by Cretaceous sediments.
