陕西商丹地区铀矿成矿规律及勘查方法组合探讨
|
摘要
秦岭造山带是我国金属矿产资源的重要基地之一。通过对商丹地区不同类型铀矿的区域地质特征、矿区地质特征及矿床地质特征的综合分析研究,划分出花岗伟晶岩脉型、花岗岩型以及构造热液型三种铀矿类型,进而提出"依托地层、抓住岩体、控制岩脉(脉岩型)、查明构造(构造热液型)、注意岩体中矿物结构构造及主要矿物含量变化部位(花岗岩型)"等寻找铀矿的找矿判据和找矿方向。同时针对该地区铀矿的成矿地质特点,提出立体式综合勘查的技术方法和手段。
Qinling orogenic belt is one of the important bases of metal mineral resources in China. Through the comprehensive analysis of regional geological characteristics,different types of uranium deposits of Shangdan area mine geology and geological features,divided pegmatite,granite type and tectonic hydrothermal type uranium deposit three. And then put forward the"relying on the strata,rocks,dikes(seize control dyke type),geological structure(tectonic hydrothermal type),pay attention to the changes in rock mass structure and mineral contents of main minerals(granite type) "looking for uranium prospecting criteria and prospecting direction. At the same time,according to the metallogenic geological characteristics of uranium deposits in this area,the technical methods and means of stereoscopic comprehensive exploration are put forward.
