摘要
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。
Wutai-Lüliang area of Shanxi Province is an important metallogenic area of Precambrian sedimentary metamorphic iron deposits in North China Craton.On the foundation of summarizing predecessors＇ accomplishments and available data,and the new forecasting theory and exploration method,a theoretical prospecting model for the sedimentary metamorphic iron deposits of the study area is formulated by analyzing the geological,geochemical and geophysical data on the flat of GIS.The metallogenic prognosis is made by using the evidence weight method combined with the grid cell method according to the established prospecting model.The prediction shows 2class-A metallogenic prospects and 5class-B metallogenic prospects on the basis of the values of posterior probability.The result provides a valuable reference to the further ore-prospecting in that area.
