南蒙古欧玉陶勒盖斑岩型矿床研究进展

New progress in the study of the Oyu Tolgoi porphyry deposit in southern Mongolia

南蒙古欧玉陶勒盖矿床是世界上已知最大的斑岩型铜金矿床之一,处在中古生代哈萨克-蒙古岩浆弧内,是中国"一带一路"项目中中国企业"走出去"的重要方向之一。铜金储量高、矿床品位好、矿化范围广、矿体规模巨大,属世界级超大型斑岩型铜(金)矿床,开发潜力巨大。在收集大量资料的基础上,通过整理和分析,建立成因模型,并划分出北Heruga区域、Javkhlant区域、西Hugo深部区域、西Hugo深部区域、Ulaan Khud北部矿点5个找矿远景区。欧玉陶勒盖矿床所在成矿带沿哈萨克-蒙古岩浆弧向两端延伸,向西经新疆土屋铜矿延伸至哈萨克斯坦境内的科翁腊德和阿克脱盖斑岩铜矿,向东延伸至中国境内多宝山、铜山地区。

The Oyu Tolgoi deposit, one of the largest porphyry Cu（Au）deposits in the world, is characterized by high copper and gold reserves, high grade, wide range and large scale mineralization of the orebody. China-Mongolia border extends for 80kin, which belongs to China＇s ＂One Belt, One Road＂ project and hence is one of the important directions for the going out policy of China＇ s enterprises. On the basis of the information collected and analyzed by the authors, it is considered that North Heruga region, Javkhlant region, West Hugo deep region, West Hugo deep region, Ulaan Khud northern region are five strategic targets. On such a basis, the authors set up a metallogenic model. The authors hold that the Oyu Tolgoi deposit is located in the metallogenic belt which extents along the Kazakh-Mongolian rnagmatic arc to the two ends. In the west, the belt extends through the Tuwu copper deposit of Xinjiang to the Kounrad porphyry copper deposit and another porphyry copper deposit in the territory of Kazakhstan; in the east, it extends to Duobaoshan and Tongshan area within the territory of China.
