冀西北地区铜地球化学块体特征及资源潜力预测

摘要

Based on the 1:200 000 geochemical exploration data of northwest of Hebei Province and the application of geochemical blocks theory and method,we systematically analyzed the characteristics of copper geochemical blocks and resources.Then three copper geochemical blocks and three anomalies were delineated.The No.3 copper geochemical block was worth higher degree of research and focused on,which was coupled to verify by combing with the characteristics of remote sensing liner -ring structure and regional remote sensing alteration information abnormal zone.Optimizing prospect of geochemical block,draw a copper mineral metallogenic prospect areas,thus achieve the goal of metallogenic prediction.%　　以冀西北地区1∶20万化探扫面资料为基础，应用地球化学块体理论与方法，对研究区内铜的地球化学块体特征和铜矿产资源特征进行了系统分析。共圈出3个规模不等的铜地球化学块体和3处地球化学异常，重点分析研究程度较高的3号铜地球化学块体，通过结合遥感线、环构造特征和区域蚀变遥感异常带对3号铜化学矿体进行耦合验证，优选找矿地球化学块体，认为3号铜化学矿体内涞源县湖海铜地球化学异常区具有进一步找矿潜力。
