Characteristics of Granite type Uranium Mineralization and Exploration Prospect in the Middle of Qimantage Mountain Range
摘要
Abstract
In the middle of Qimantage mountain range,one uranium occurrence and four mineralization spots have been found,there are Heishan occurrence,Langyashan South,Xidagounao and Xigou spots. The mineralization is distributed near the contact zones between Variscan Indosinian granitoids and Pal-eoproterozoic Jinshuikou group,which are controlled evidently by the faults and often accompanied with hematitization,silicification and chloritization.Electron microprobe analysis showed that ore in Heishan occurrence contains native uranium mineral of pitchblende and secondary uranium mineral of uranophane, Tyuyamunite,boltwoodite.Because uranium content of Paleoproterozoic metamorphic Jinshuikou group and Indo Yanshanian adamellite content can reach (5~12)×10-6 which provide good uranium source;the region also experienced multi tectonic magmatic activity of Caledonian,Variscan,Indo China and Yanshan and faults are well developed.Therefore,the middle of Qimantage mountain range has good ex-ploration prospects.关键词
