胶西北上庄金矿断裂—岩体控矿规律

Gold Distributing Regulation with Structure and Intrusions in the Shangzhuang Gold Deposit, Northwest of Shandong Province,China

采用GeoMine3D软件对胶西北上庄金矿进行了三维地质建模。三维地质模型全面展现了矿体、望儿山断裂带及下伏郭家岭岩体的空间关系:金矿体受望儿山断裂带控制,在断裂带中具有丛聚性、似等距性、侧伏性的分布特征,其主要赋存在断裂带产状变化大的位置;郭家岭岩体与金矿的成岩成矿关系密切,岩体顶界面控制主要矿体的产出,其转折端或岩突处为金矿富集的有利位置。研究结果显示:上庄金矿深部仍具有较大的找矿潜力。

3D geological model is introduced to the orogenic gold deoposit and provides a full view of the relationship of gold and the Guojialing intrusion as well as the Wangershan fault belt. The gold seemed to be distributed amalgamated, regulated, and zoned in the Wangershan fault belt and tends to be amalgamated in the bump of the faults and the arc of the Guojialing intrusion. With the regulation of gold distribution, it tends to have more gold in the deep trend of the Wangershan fault belt.
