| 摘 要： | 甘肃文县—康县地区的内生金矿床可分为两类，即兼有变质热液和岩浆热液参与成矿的混合热液型和韧性剪切带型。其典型代表分别为新关金矿和尚家沟金矿。通过对本区地层、构造、岩浆岩的综合研究及典型矿例的分析，认为本区成矿条件良好，尤其是具有形成大型剪切带型金矿的广阔前景，找矿中应特别注意碳硅泥岩中韧性剪切带发育并伴有破碎蚀变及低温元素组合Ａｕ－Ａｓ－Ｓｂ－Ｈｇ－Ａｇ的浓集中心地带

| Abstract: | The endogenic gold deposits in the Wenxian-Kangxian area, Gansu Province can be divided into two types,hydrothermal type with metamophic hydrothermal and magmatic hydrothermal and ductile shear zone type. Their typical examples are the Xinguan gold deposit and the Shangjiagou gold deposit. Based on the comprehensive studies of strata, structure, magmatic rocks and the analysis of typical deposits,it is believed that this area provides good metallogenic geologic condition for forming large scale ductile shear deposits. The development of ductile shear zone,altered fracture and concentration center of low temperature element association such as Au-As-Sb-Hg-Ag in carbonaceous-siliceous-argillaceous rocks should be paid attention to in the process of searching for gold mineral resources. |
