特征分析法在内蒙古巴彦温多尔矿区成矿预测中的应用

Application of characteristic analysis in metallogenic prediction of Bayanwenduoer mine,Inner Mongolia

在内蒙古中部造山带内的三叠纪黑云母二长花岗岩与下二叠统大石寨组安山岩、凝灰岩的内外接触带上,经过详细的基础地质工作,采用土壤和岩石地球化学测量,同时配合1:10000高精度遥感,进行了1:10000的大比例尺找矿工作。通过对矿区地球化学样品空间联系度高值区进行找矿工程查证,发现样品空间联系度高值区与新发现的矿体吻合较好,表明利用特征分析对地球化学测量数据进行处理,指导找矿效果明显,值得在邻区进一步推广。

Based on detailed geological work, in the inner and outer contact zone of Triassic black mica two long granite, Two Permian Dashizhai formation andesite and tuff in the central Inner Mongolia orogenic belt,by using the soil and rock geochemical sur- vey, along with 1：10000 high precision remote sensing, 1：10000 large scale prospecting work has been carried on . Through the pros- pecting engineering verification of mining area geochemical sample space of high value area, the authors have found that the sample space of high value and the new discovery of ore body tallies well. It indicates the use of characteristic analysis of geochemical data pro- cessing can guide the ore - prospecting effectively, and it is worthy of further promotion in the neighbouring area.
