摘要
通过库布苏金矿不同岩脉、地层、石英脉内微量元素及稀土元素含量与组成的研究 ,得出库布苏金矿岩脉形成与区域岩浆活动有关 ,岩脉与区域中基性岩脉、泥盆纪火山 -沉积地层在成矿物质上具有同源性或继承性。石英脉与岩脉、地层在元素地球化学特征上差别较大。矿化与石英脉是不同阶段的产物 ,其为后期热液作用的产物。东准噶尔地区的金矿找寻应以围岩蚀变作为主要找矿标志。
On the basis of study of trace element and REE in the different dykes, wallrock and quartz vein in Kubusu deposit, it points out that the dykes in Kubusu deposit is related to the magmatic activity in the region, and have a same origin or inherent relative among the dykes in Kubusu deposit, the mid basic dykes in the region and Devonian volcanic sediment. The quartz vein makes great difference with the dyke and wallrock in respect of the element geochemistry character. Mineralization took place after the quartz vein forming, the result of hydrothermal activity. The wallrock alternative can be regarded as the main mark of discovering gold deposit in the future.
