雪峰古陆西南缘区域地球化学场对成矿的控制作用

REGIONALLY GEOCHEMICAL FIELDS AND THEIR CONTROL OVER MINERALIZATION ON THE SOUTHWESTERN MARGIN OF THE XUEFENG OLD LAND

研究区内不同时代的地层中 ,元素Au、Ag、Sb、Cu、Pb、Zn等具有不同的含量及统计参数特征 ,在区域上构成了 2个大的地球化学场和 1 0个次级场 ,它们控制了不同类型矿床的分布 。

In the strata of different ages outcropping in the studied region, the elements Au, Ag, Sb, Cu, Pb, Zn, have different contents and statistical parameters, which make up 2 major geochemical fields and 10 second-order geochemical fields. These fields control the distribution of different types of ore deposits, which shows the inherent association with the geochemical fields and mineralization.
