甘肃省红崖沟地区地质特征及地球化学分布特征

Geological Characteristics and Geochemical Distribution Characteristics of Hongyagou Area in Gansu Province

红崖沟地区地层属秦祁昆地层大区-秦岭地层小区-勉略地层分区,大地构造位置特殊,成矿条件良好,找矿条件广阔。异常主要分布于工作区西南部,总体沿北西向展布。Au、As、Hg、Mo、Sb、W元素异常发育,规模大、强度高、具有三级浓度分带,其中Au、As、Hg、Sb、元素异常重合性好。

The stratum of Hongyagou area belongs to the Qinqikun stratigraphic area-Qinling stratigraphic district-Mianlue stratigraphic subdivision, with special geotectonic location, good metallogenic conditions, and broad prospecting conditions. The anomalies are mainly distributed in the southwest of the working area, and generally distributed along the northwest direction. Au, As, Hg, Mo, Sb, and W are abnormally developed, with large scale, high intensity, and three-level concentration zoning. Among them, Au, As, Hg, Sb, and elements have good coincidence.
