湖北两竹地区水系沉积物地球化学特征及找矿方向

摘要

结合工区内的基础地质情况，通过分析区内1∶5万水系沉积物地球化学参数特征及其元素的相关性，认为相关元素地球化学异常（高值区）严格受竹山断裂带、曾家坝断裂带，以及加里东期的热液活动、脉岩、震旦—寒武系地层等因素联合控制。根据异常特征与成矿地质条件，在工区内圈定了11处找矿远景区，为该区下一步的找矿工作指明了方向。%Combining with basic geological information of Liangzhu area , the authors analyzed the geochemical parameters’features of 1∶50 000 stream sediments survey as well as the relationships between elements ,and suggested that the anomalies ( high value areas ) of related elements are strictly controlled by Zhushan fault zone , Zengjiaba fault zone ,Caledonian hydrothermal activities and Simian-Cambrian strata .According to the anomalies and the ore-forming geo-logical conditions ,the authors delineated eleven ore-searching prospective targets which play an important role in further ore-prospecting work .
