摘要
通过对川西高原草原地区的东北寨、马脑壳和哲波山金矿区的研究，总结该区的特殊的弱酸性偏还原的表生地球化学特征。并研究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，总结出该区的表生地球化学特征。
Based on studies of three gold ore districts in West Sichuan plateau prairie area,this paper has summed up the weakly acid and somewhat reductive supergene geochemical characteristics of this area,the impoverishment and enrichment of different groups of elements,and the variation regularity of elements in soil of different size fractions and depths.It is pointed out that Au,As,Sb,Hg and W are main ore forming elements in gold deposits of this area.
