新疆寨北山铜矿成矿新认识及找矿预测

New understanding of Zhaibeishan copper mine and ore-prospecting prediction,Xinjiang

通过对寨北山次火山岩型铜矿以往勘查资料研究,结合对矿区脉岩分布、岩浆活动、脉状富铜矿、深部原生晕、流体包裹体等特征的新认识,认为寨北山铜矿是多期岩浆活动成矿的产物,深部可能存在隐伏富铜矿体和含矿岩体。依据成矿地质体、成矿构造和成矿结构面、成矿作用"三位一体"的特征,初步建立找矿预测模型,为今后的勘查工作提供一种思路。

Based on the previous exploration data of zhaibeishan subvolcanic type copper deposit and the new understanding of the distribution of vein rock,magmatic activity,vein rich copper deposit,deep primary halo,fluid inclusion and other characteristics,it is believed that zhaibeishan copper deposit is the product of multiple magmatic activities and mineralization,and there may be hidden rich copper deposit and ore-bearing rock in the deep part. According to the characteristics of " triad" of metallogenic geological body,metallogenic structure,metallogenic structure plane and metallogenesis,a preliminary prospecting prediction model is established to provide an idea for future exploration.
