VERTICAL ZONING OF THE COPPER-MOLYBDENUM FORMATION OF THE KUZNETSK ALATAU (KHAKASSIA)

Siberian Research Institute of Geology, Geophysics and Mineral Resources, Novosibirsk, Russia
The previously identified zoning of the copper-molybdenum formation based on a comparison of geological features of the Sorskoye, Ipchulskoye and other deposits, is confirmed by a comparison of their deep structure and general model of the ore-magmatic system. As a result, it was possible to determine the distribution of ore matter and the degree of concentration of fluids and metals in the evolutionary chain in the first approximation: the initial granite melt-leucogranite residual chamber – ore-forming apophyse from the chamber. The maximum concentration in apophyse is 1000–2000 times higher than the initial content in an ordinary granite. This makes it possible to consider the fluidized apophyse melt as “ore magma” responsible for the ore formation.
Keywords: ore-magmatic system, zoning of the copper-molybdenum formation, concentration of fluids
and metals, ore magma.
