新疆金滩金矿矿床地质特征及控矿规律研究
|
摘要
金滩金矿床是康古尔塔格金矿带内一个中型规模的金矿床,矿床历时多年开采,资源消耗殆尽,后备储量严重不足,急需开展深边部找矿预测研究。在研究矿床地质特征的基础上对其控矿规律进行了深入探讨,研究认为构造是本矿区的主体控矿因素,构造的分级控矿作用明显,不同级别的构造单元分别控制着矿带、矿床和矿体的产出。矿山现有矿体均位于矿区紧闭向斜的南翼,因此其北翼(矿区西北部)亦具有良好的找矿前景,经工程验证,找矿效果明显。
Jintan gold deposit is a medium-sized gold deposit in the Kangguertage gold mineralization belt,which is representative in the whole East Tianshan area. The resources are exhausted because of multi-year exploitation,and the backup resource reserve of the mine is severely inadequate. Therefore,the research of prospecting prediction in outer and deeper areas of this deposit is urgently needed. Based on the geological characteristics of the deposit,this paper studies the ore-controlling regularity in depth. The results show that the structure is the main controlling factor of the mine,and the grading ore-controlling of the structure is obvious,and the structural units of different levels control the output of ore belt,ore deposit and ore body respectively. The existing ore bodies of the mine are located in the south wing of the closed syncline of the mining area,therefore,the north wing of the closed syncline(northwest of the mining area) has good prospects. Through the engineering verification,the prospecting effect is obvious.
