【摘要】 本文基于GIS技术综合分析了焦家金成矿带的成矿地质条件和矿体赋存规律,建立了研究区金矿预测模型,并提取了相关成矿预测因子,采用证据权法对成矿预测因子进行了赋值,圈定了找矿预测区,并择优对预测区进行了钻探验证。研究表明,焦家金成矿带有关的矿床预测权重包括岩浆岩、构造、蚀变带以及物化探异常等;研究区划分了6个预测区:后坡预测区、任家预测区、卧龙预测区、綦家预测区、龙埠预测区、城子预测区;经钻探验证,在后坡预测区发现金矿体3个,与预测结果基本一致。更多还原

【Abstract】 Based on GIS technology,this paper comprehensively discussed metallogenic geological conditions and ore deposit occurrences of Jiaojia gold metallogenic belt,and established the prediction model of gold deposits in the study area.The authors extracted the factors related to metallogenic prediction and assigned them using weights of evidence method.And accordingly,we delineated ore prediction areas and assessed them by drilling verification.The prediction factors included magmatite,structure,alteration zone and anormalies of geophysical and geochemical exploration.We proposed 6prediction areas which distributed at Hopo,RenJia,Wolong,Qijia,long Bu,Chengzi.The result of drilling verification showed that 3gold mines were found at Hopo forecast area,consistenting with the prediction results.更多还原
