藏东玉龙斑岩型铜矿带综合信息找矿预测

Comprehensive information prospecting prediction of the Yulong porphyry copper belt in eastern Tibet

对藏东玉龙斑岩型铜矿带进行二维综合信息找矿预测与分析,提取与深入分析多源找矿信息,揭露研究区的隐伏矿体,为该区日后的矿产资源勘查与开发提供有利证据。通过对研究区的地层、构造、岩浆岩、地球化学信息及蚀变等要素与成矿之间的关联性进行研究,建立该区的证据权找矿模型。利用证据权重法进行找矿预测,圈定了8处成矿有利地段,其中A类靶区4处、B类靶区2处、C类靶区2处。A类靶区可作为重点勘查区,B类靶区为研进一步找矿区。

The two-dimensional comprehensive information prospecting prediction and analysis of the Yulong porphyry copper belt in eastern Tibet have been carried out,and the multi-source prospecting information has been extracted and deeply analyzed to find the hidden ore bodies in the study area and provide favorable evidence for the future development and exploration of mineral resources in this area.In this paper,the correlation between strata,structures,magmatic rocks,geochemical information and alteration and mineralization in the study area was studied to establish the evidence weight prospecting model.The weight of evidence method was used for prospecting prediction,and 8 favorable metallogenic sections were delineated,which includes four targets of Class A,two targets of Class B,and two targets of Class C.Target area of Class A can be used as key exploration areas,and Class B can provide further refe-rence for ore prospecting in the mining area.
