摘要：
The distribution of volatiles in ore units of the Western Pana layered mafic pluton in the Kola province was studied with pyrolytic gas chromatography. In comparison with barren rocks, the rocks containing Pt-Pd mineralization are characterized by a much higher concentration of volatiles, especially H(2)S, SO(3), and CH(4). With a drop in temperature, the redox potential of the fluid phase in the ore-magmatic system increased. PGE mineralization was largely formed at the postcumulus stage with participation of volatiles under variable redox conditions.
