| 中文摘要: |
| 五莲七宝山金铜矿与隐爆角砾岩筒的关系引起了许多学者的重视,对该矿的探讨不仅有助于开展火山作用与成矿关系的研究,而且对今后指导普查找矿工作也有实际意义。我们对七宝山金铜矿用较短的时间,以较少的工作量,探明一个低品位中型的金铜矿床,获得了较好的地质效果和经济效益,为矿山扩建生产打下了良好的基础。 |
| 英文摘要: |
| Qibaoshan gold-copper deposit is located in the lower Cretaceous volcanic basin in southwest part of Jiao-Lai depression region, to the east of Yisnu fracture zone and west of Jiaonan uplift.Fractures in the basin are well-developed and the volcanic activity intensive.Gold deposit is related to medium-acid subvolcanic rocks of the late magmatism in the area, occurring in the crypoexplosion breccia pipe predominantly composed of quartz diorite-porphyrite.Therefore, the auther believes that this is a geld-copper deposit associated with crypoexplosion volcanic breccia pipe. |
