内蒙古呼和哈德一带银多金属矿成矿地质特征及找矿方向
|
摘要
内蒙古呼和哈德一带地处西伯利亚板块东南缘,通过1∶5万区域地质矿产调查工作新发现了一批银多金属矿点及找矿线索。根据该区基础地质调查研究成果,分析了区域成矿地质背景及其成矿专属性,结合区域地球物理、地球化学、矿化蚀变等综合找矿信息,讨论了该区银多金属矿产的成矿地质特征。针对该区特殊的地形地貌景观,在总结前人找矿经验的基础上,运用地质构造解析、1∶5万航磁测量、1∶1万激电中梯剖面测量、1∶5万水系沉积物测量以及1∶1万土壤剖面测量等技术方法组合,实现了找矿突破,经槽探揭露发现了银多金属矿化体。研究表明:该区银多金属矿化与古生代地层关系密切,明显受控于NE向和NW向2组断裂,尤其是2组断裂交汇部位(视极化率大于1.5%,并伴有Ag、Cu、Pb、Zn、As地球化学异常)为成矿有利地段,指示了进一步的找矿方向,显示出该区具有较好的找矿潜力。
Through 1∶50 000 regional geological and mineral resources survey,a batch of sliver polymetallic ore occurrences and prospecting cues are newly found in Huhehade Area,which locates in the southeast margin of the Siberian Plate.Based on the study results of the basic geological investigation data of the area,the regional metallogenic background and its metallogenic specialization are analyzed,combing with geophysical,geochemical and mineralization alteration informaiton,the metallogenic geological characteristics of Ag-polymetallic minerals of the area is discussed.Aiming at the special landscape of the area,based on summing up the previous prospecting experience,the technique methods combination of structure geological structural analysis,1∶50 000 aeromagnetic survey,1∶10 000 IP ladder profile measurement,1∶50 000 stream sediment survey and 1:10 000 soil profile measurement are adopted,the prospecting breakthrough is acquired.Silver mineralization bodies are discovered by means of prospecting trench.The study results show that the silver polymetallic mineralization is closely related to Paleozoic strata and obviously controlled by NE and NW faults,especially for the junction of the two groups of faults is the favorable metallogenic location,where the sound polarizability values is above 1.5% and accompanied by Ag,Cu,Pb,Zn and As geochemical anomalies,which further indicated that the prospecting potential of the area is good.
