Conditions of the Formation of Unique Mineralization with Yushkinite V1 – xS · n[(Mg,Al)(OH)2] in Quartz–Calcite Veins, Pai-Khoi Ridge: Evidence from Study of Fluid Inclusions

Abstract

The results of the study of fluid inclusions in quartz from quartz–calcite veins with unique yushkinite mineralization are reported. For the first time, it was proved that their formation occurred under sharply reducing conditions. The mineral formation medium was enriched in calcium and magnesium chlorides and hydrogen sulfide. The temperature of mineral formation was ~120–150°С.
