N_2, H_2S, AND H_2O IN СО_2-BEARING FLUID AND COEXISTENCE SULFIDE INCLUSIONS IN THE UPPER MANTLE (EAST ANTARCTICA)

摘要

Thus, the mantle substratum was affected by СО_2-N_2-H_2S-H_2O fluid at a temperature not below 1060°C and pressure 1.5 GPa, at depths of 45-60 km. The H_2S-containing fluid coexisted with the Ni-enriched sulfidic melt and mss at temperature from 1060°C up to 920°C.
