证据权重法在下柳沟-尕大坂铜多金属矿床找矿中的应用

Weights of evidence method in willow ditch-essential Osaka copper polymetallic deposit prospecting application

成矿预测方法和手段日益增多,找矿需要选择合理的预测方法。本文利用证据权重法对下柳沟-尕大坂铜多金属矿床开展了相关的研究,建立找矿模型,计算各个预测单元的后验概率P,圈定了Ⅰ级靶区,Ⅱ级靶区,Ⅲ级靶区,为下一步找矿工作提供了一定的依据。

The prediction method and means of metallogenic prediction are increasing, and it is necessary to choose the reasonable prediction method. Using evidence weight method under the willow ditch-essential Osaka related researches on copper polymetallic deposit, prospecting model is set up, to calculate the posterior probability of all the prediction units P, framed the Ⅰ level target, Ⅱ level target, Ⅲ level target, for the next step prospecting work have provided the certain basis.
