浙江龙游庙下陈村多金属矿区地质、物化探特征及其找矿远景
|
摘要
在系统收集、综合分析已有资料的基础上,对龙游庙下陈村矿区重点成矿地段开展1∶2 000地质修测,通过地质、物化探和钻探等综合方法,了解第四系覆盖区下方庙下断裂的产出状况、含矿构造蚀变带分布以及酸性岩脉群下方可能存在的隐伏斑岩系统,共圈定出成矿潜力较大的物化探综合异常带2处。根据地表土壤Pb、Zn高异常,已知矿化蚀变带分布及矿化分带性,特别是ZK001钻孔勘探显示的5层铅锌矿化体,认为矿区是开展深部找矿工作的有利地段。
Based on systematic collection and integrated analysis of data available,the authors conducted 1∶2 000 geological modification survey in the key metallogenic segments of the Chencun ore district in Miaoxia,Longyou County,Zhejiang Province,and used integrated methods composed of geological investigation,geophysical-geochemical exploration and drilling to understand the modes of occurrence of Miaoxia fault beneath the Quaternary overburden,the distribution of ore-bearing structure alteration zone and the possibly-existent concealed porphyry under the acid dyke group.There were two geochemical and geophysical anomalies of much metallogenic potential to be delineated.The high abnormal of Pb,Zn in surface soil,mineralized alteration zone and mineralization zonation,especially the 5 layers of lead-zinc mineralization body found in the ZK001 drilling of view showed that the mine is favorable locations to carry out deep prospecting work.
