摘要(Abstract):
山西省五台-吕梁地区是华北克拉通重要的前寒武系沉积变质型铁矿成矿区。全面总结了研究区前人成果和现有资料,利用新的成矿学理论和固体矿产预测方法技术,使用GIS软件平台统计分析了地质、地球化学、地球物理等多元信息,并以此建立了研究区的沉积变质型铁矿找矿概念模型;结合网格单元法和证据权重法对研究区进行了铁矿资源预测,并依据计算得到的后验概率值和成矿地质条件的综合分析圈定了2处A级成矿远景区(五台山远景区、袁家村远景区)和5处B级成矿远景区(桑干河-灵丘县远景区、武灵镇-神堂堡乡远景区、恒山铁矿远景区、轩岗镇-长梁沟镇远景区、关帝山-庞泉沟远景区)。预测结果对该区域进一步找矿具有一定指导意义。
