STUDY ON EXPERIMENTAL GEOCHEMISTRY OF Au, Sb AND W IN WATER-ROCK INTERACTION OF OPEN LOW-TEMPERATURE SYSTEM

The stratabound gold deposits with element association of Au-Sb-W, Au-Sb, and single Au represented by the Woxi, Xichong and Mobin gold deposits respectively are widely distributed in the Proterozoic group in west Hunan Province, China. The studies on their mineral assemblage, wall-rock alteration and the physicochemical conditions under which they formed reveal that they all should belong to moderate-to low-temperature deposits and their principal mineralization was generated under low-temperature condition.
