“ORE MAGMA”. WHAT IS IT FROM THE STANDPOINT OF THE GRANITE ORE-MAGMATIC SYSTEM?

The concept of “ore magma” remains an obscure hypothesis in ore formation. The article considers the process of natural overgrowth of trivial primary basaltic magma into an ore-bearing granite melting and further into the ore-forming “ore magma” as the concentration of volatile and ore components. The dark side of the problem lies in the fact that during the ore formation the “ore magma” liquates into contrasting phases and leaves practically no traces of itself (with rare exceptions). But the concept of the ore magma has received a logical scientific justification from the standpoint of ore-magmatic systems.

Keywords: еvolution of basaltic magma to granite melting, concentration of volatile and ore elements, “ore magma” in the composition of ore-magmatic system.
