哈腊苏铜矿位于青格里河-布尔根复背斜轴部的北西端,主要的赋矿层位是泥盆系中泥盆统北塔山组第三亚组(D2b3)第一岩性段,岩性以无斑玄武岩、玄武安山岩为主。大功率激电工作显示存在低阻、高极化异常带,异常与地表矿化部位吻合很好。激电测深表明在地下140 m-200 m存在高极化、中低阻层,推断为含铜花岗闪长斑岩体,深部找矿前景良好。本文结合本区的组合物探异常特征,提出对寻找斑岩型金属硫化物矿床较为有效的找矿模式。
The Hallasu copper deposit is located on the northwestern tip of the Sigurdi-Burgan complex anticlinal axis. The main ore-hosting horizon is the first lithologic segment of D2b3 in the North Tashan Formation of the Devonian. Lithology to non-spot basalt, Basalt Andesite. High-power laser work shows the presence of low resistance, high polarization anomaly, anomalies and surface mineralization good agreement. Electrophysological sounding shows that there is a high polarization and medium-low resistivity layer in the underground 140 m-200 m, which is inferred to be a copper-bearing granodiorite porphyry. The prospects of deep prospecting are good. Combined with the characteristics of the anomaly of the geophysical prospecting in this area, this paper proposes a more effective prospecting model for finding porphyry metallogenic sulfide deposits.
