川西高原草原地区的金矿成矿元素的表生地球化学特征

SUPERGENE GEOCHEMISTRY OF ORE FORMING ELEMENTS IN GOLD DEPOSITS IN THE GRASSLANDS ON THE WEST SICHUAN PLATEAU

通过川西高原东北寨、马脑壳和哲波山金矿区的研究，总结了该区的特殊的弱酸性偏还原的表生地球化学特征，研究了不同组元素的贫化和富集，不同粒级、不同深度的元素变化规律，提出金、砷、锑、汞、钨等元素是该区金矿的主成矿元素。

Study of the Dongbeizhai,Manaoke and Zheboshan gold deposits indicates that supergene geochemical environment in the grasslands on the West Sichuan Plateau is weak acid and reducing and Au,As,Sb,Hg,W are main ore forming elements in the gold deposits
