中文摘要:文章以张家口铅锌银多金属富集区为例,在前人研究的基础上,运用GIS平台提取了与成矿关系密切的赋矿层位、岩体5 km缓冲区、深大断裂3 km和次级断裂1 km的复合缓冲区及化探、物探异常等证据图层,选用证据权重法模型对研究区进行了成矿远景区分析和评价,取得了较好效果,并讨论了预测过程中信息提取时应注意的问题。
Abstract:Based on the lead_zinc-silver metallogenic regularity of Zhangjiakou area in Hebei Province, the authors studied strata, buffering zone of magma and faults, and geochemcial and geophyscial anomaly zones by using geographic information system software. Through an analysis of integrated evidence factors through evidence weight, the authors finally completed ore_prospecting target prognosis of the study area and also discussed some problems concerning the extraction of ore_controlling information in the prognostic process.
