The Constraints on the Differential Enrichment of Au and As During Hydrothermal Mineralization,Southwest Guizhou,China

The differential enrichment of gold and arsenic observed in As-bearing hydrothermal gold deposits in Southwest Gizhou is induced by vapor-liquid separation in response to changing physico-chemical conditions during the hydrothermal evolution and is a reflection of the geochemical behavior of the two elements.     

黔西南含砷热液金矿床Au,As矿化分离现象探讨

在黔西南含砷热液金矿床中，砷异常与金矿化具有明显的空间分带性。研究结果表明，导致金、砷空间分带的原因由Ａｕ、Ａｓ矿化分离引起，并受控于Ａｕ、Ａｓ各自的地球化学行为及热液体系的物理化学条件的改变。
