Abstract
Fluid and melt inclusions in minerals from magmatic rocks and associated ores and metasomatites were studied. Based on the results obtained as well as on experimental data, possible evolution trends are considered for the phase composition of magmatogene fluids separating from granitoid and basic melts at different depths. Three types of fluids have been recognized according to their composition and phase state, which differ in metal contents: (1) homogeneous supercritical, (2) heterophase
