Physicochemical conditions of differential mineralization of Au and As in gold deposits, southwest Guizhou Province, China

  • He Mingyou


The conditions under which gold and arsenic are enriched separately during mineralization in gold deposits in southwestern Guizhou Province were described and the thermodynamic calculations gave: 200–150°C at 400 × 10−6 -300 × 106 Pa (corresponding to a depth between 1.6 km and 1.2 km); lgf o2,−40 to -35 Pa; lgf s2, -20 to−16 Pa; pH 5.0 -4.2 and Eh -0.53 V.
