基于证据权重法的成矿预测——以广东省钨锡矿的成矿预测为例

在建立广东省地质、矿产、物探、化探、遥感等基础空间数据库的基础上,深入研究了其成矿规律及成矿地质环境,充分利用现代的GIS矿产资源评价技术提取了与矿产有关的信息,运用证据权重法对研究区进行综合定位预测,根据预测结果圈定了74个成矿远景区。预测结果对于该区的进一步找矿工作具有重要的指导意义。

Minerogenetic prediction based on the weight-of-evidence approach:a case study of the prediction of tungsten and tin deposits in Guangdong, China

Based on the spatial database of geology, mineral resources, geophysical and geochemical exploration and remote sensing in Guangdong, the authors performed a deep-going study of the metallogenic characteristics and metallogenic geological environment and made full use of the modern GIS mineral resource assessment technology to extract information related to mineral resources. Furthermore, they carried out integrated localization and prediction in the study area using the weight-of-evidence approach and selected 74 ore prospect areas according to the prediction results. The prediction results have great guiding significance for further mineral search in this area.
