山东沂南金矿地质构造控矿机理及其对深部找矿的启示

Ore controlling mechanism of geological structure of Yinan Gold Deposit in Shandong Province and Its Enlightenment to deep prospecting

为了提升山东沂南金矿的深部找矿工作效率,分析山东沂南金矿地质构造控矿机理及其对深部找矿的启示作用。深入研究山东沂南金矿在地层、构造、岩浆岩等方面的特征,并从物质来源、成矿温度等方面,确定其成矿机制。在此基础上,确定地质构造的控矿模式与机制。在考虑地质构造控矿机理的前提下,通过深部靶区预测,确定山东沂南金矿的深部找矿方向。通过启示作用分析实验得出结论:相比于传统的深部找矿方式,将地质构造控矿机理考虑其中,可以有效的加快找矿速度,并提高矿石的开采量。

In order to improve the efficiency of deep prospecting in Yinan Gold Mine,Shandong Province,the ore controlling mechanism of geological structure and Its Enlightenment on deep prospecting are analyzed.The characteristics of strata,tectonics and magmatic rocks of Yinan Gold Deposit in Shandong Province are deeply studied,and the metallogenic mechanism is determined from the aspects of material source and metallogenic temperature.On this basis,the ore controlling model and mechanism of geological structure are determined.On the premise of considering the ore controlling mechanism of geological structure,the deep prospecting direction of Yinan Gold Deposit in Shandong Province is determined through deep target prediction.Through the enlightenment analysis experiment,the conclusion is drawn:compared with the traditional deep prospecting method,considering the geological structure control mechanism can effectively speed up the prospecting speed and improve the ore production.
