| 中文摘要: |
| 红山铜矿是在新疆东准噶尔老爷庙一带新发现的铜矿床,红山铜矿铜矿体均赋存于红山铜矿化蚀变带内,并严格受黑园山深大断裂控制。红山铜矿的赋矿围岩为下石炭统黑山头组蚀变火山碎屑岩,铜金矿化与中酸性浅成斑岩体具有成因联系,围岩蚀变中的黄铁绢英岩化、硅化、黄铁矿化与铜金成矿关系密切,铜矿体规模大、数量多,2号和8号矿体为主矿体,钻孔中见到厚大富铜矿体,矿床深部具有较大的找矿潜力。研究表明,中酸性浅成斑岩体控制着铜矿体的规模和质量,且对金属矿物分带也产生影响,成矿时代晚于斑岩体的侵位时间,大致为石炭纪末—二叠纪初。红山铜矿的矿床类型为与中酸性浅成斑岩有关的岩浆热液型(斑岩型)铜金矿床。 |
| 英文摘要: |
| Hongshan Cu deposit is a newly discovered deposit in Laoyemiao area in east Junggar basin in Xinjiang Autonomous Region. Ore bodies occur all in Hongshan Cu mineralization-alteration zone and are controlled by deep fault and hosted by altered volcanic clastic rock of Lower Carboniferous Heishantou Formation. The Cu mineralization is genetically related to shallow intermediate-acidic porphyry, Au-Cu mineralization closely to phyllic alteration, silicification and pyritization. The ore bodies are characterized by large size and numerous number. Ore body 2 and 8 are the main ones. Drill holes hit thick and rich ore bodies thus potential to depth. This study shows that shallow intermediate-acidic porphyry body controls size and quality of the Cu ore body and influences zoning of the metal mineral. The ore formation is later than emplacement of the porphyry body taking place at end of Carboniferous Period and beginning of Permian Period. |
