IMMISCIBLE PHASES OF HETEROGENEOUS MAGMATIC FLUID, THEIR ORE SPECIALIZATION, AND SEPARATE MIGRATION DURING FORMATION OF THE YERMAKOVKA F-BE DEPOSIT

Abstract

The study of processes related to the heterogenization of fluid released from magma is of special interest because the presence of immiscible fluid phases in melt facilitates the determination of geochemical (ore) specialization of magmatic fluids. As was established from investigation of melt and fluid inclusions in minerals of granitic rocks, the heterogenization of magmatic fluid is a rather common phenomenon, especially of CO 2 is present [1-6 and others]. However, information on interphase distribution of metals remains scant and is mainly applicable only to the alkaline chloride fluids [7-10]. Furthermore, it is so far ambiguous whether the immiscible phases can be separated during migration in the fissure and pore space of consolidated pluton and country rocks.
