【摘要】 应用地质、化探、物探、遥感等手段和资料进行多元信息成矿预测已成为找矿工作的重要方法。以贵州铜仁地区锰矿为研究对象，基于研究区与成矿相关的多元信息，建立区域找矿模型；运用GIS技术对多元信息进行综合处理并提取有利成矿信息，形成找矿标志专题图层，构成找矿预测指标集；利用证据权重法建立锰矿综合预测模型，结合研究区成矿地质条件、已知锰矿床(点)等因素，确定找矿有利地区，并圈定7个远景区，为发现大规模锰矿产地提供参考。更多还原

【Abstract】 The application of geological, geochemical, geophysical, remote sensing and other means and data to achieve multivariate information metallogenic prediction has become an important method in ore prospecting. Taking the manganese deposit in Tongren area of Guizhou as the research object, the regional prospecting model was established based on the multivariate information related to mineralization in the study area. GIS was used to comprehensively process multivariate information and extract favorable ore-forming information to form the thematic layer of prospecting indicators, which constitutes the prospecting index set. The comprehensive prediction model of manganese deposit was established by weight of evidence method, and the favorable ore-prospecting areas were determined by combining the ore-forming geological conditions and known manganese deposits(occurrences) in the study area, and seven prospective areas were delineated to provide reference for the discovery of large-scale manganese deposits.更多还原
