青海省都兰县阿木尼克地区钼及多金属成矿地质条件及找矿前景分析

摘要

Amunick region is located in the southern qilian and qaidam massif north rim transition zone , fracture structure in the area is very development , frequent magmatic is activity , and hydrothermal is ac-tivity ,too . Molybdenum ore bodies mainly occur in the carbonation cataclastic siliceous rocks , alteration in volcanic breccia and tectonic altered fracture zone , mineralization types are mainly after the volcanic hydro-thermal type deposit .In this paper , according to the last two years of the study and the geological prospec-ting data of the census , on the basis of comprehensive analysis , and combining with the regional geological and metallogenic background conditions , the local area of molybdenum and metal metallogenic geological conditions and the prospecting prospect is analyzed .%都兰阿木尼克地区位于南祁连和柴达木地块北缘交接地带，区内断裂构造非常发育，岩浆活动频繁，热液活动强烈。钼矿（化）体主要赋存于碳酸盐化碎裂硅质岩、蚀变火山角砾岩和构造蚀变破碎带中，矿化类型主要为火山期后热液型矿床。本文主要根据近两年来对该区进行预查和本次普查工作的地质找矿资料综合研究分析的基础上，以及结合区域地质成矿背景条件，对本地区内的钼及多金属成矿地质条件及找矿前景进行了分析。
