| 中文摘要: |
| 天运金矿位于东天山天目金矿西北约 3 km处，天目韧性断裂带北西段。矿床含矿围岩为一套早石碳统小热泉子组片理化中酸性火山-火山碎屑岩。矿区围岩蚀变强烈主要为硅化、绢云母化、高岭土化、碳酸盐化、绿泥石化、绿帘石化，同时伴有黄铁矿化、黝铜矿化、孔雀石化等。矿化蚀变垂直于北西向的断裂构造带由黄铁绢英岩化变为青磐岩化，岩性由石英脉变为火山岩。矿体为韧性剪切带内的石英脉，矿石由黄铁绢英岩和石英脉组成，矿石矿物主要为自然金、黄铁矿、褐铁矿、孔雀石。地表大范围的青磐岩化、强烈黄铁绢英岩化、褐铁矿化、孔雀石化蚀变是直接找矿标志，矿区也具有明显的 Au-Zn-Mo-W元素地球化学和遥感影像异常。天运金矿的发现显示天目金矿带成矿地质条件优越，仍有较好的找矿潜力。 |
| 英文摘要: |
| The Tianyun gold deposit is located about 3 km northwest of Tianmu gold deposit in East Tianshan, and the NW segment of Tianmu ductile fracture zone. The ore-bearing wall rock of the deposit is a set of physical and chemical intermediate-acid volcanic-volcanic clastic rock of the Early Carboniferous Xiaorequanzi Formation. The mineralized alterations contain silicification, sericitization, kaolinization, carbonatization, chloritization, epidotization and pyritization, tetrahedrite mineralization, malachite. The mineralization-alteration-vertical NW-trending fault structure zone changed from beresitization to propylitization, and from quartz vein to volcanic rock. The ore-body is quartz vein in ductile shear zone. The ore is composed of beresite and quartz veins. The ore minerals contain native gold, pyrite, limonite and malachite. Large-scale propylitization, intense beresitization, limonitization and malachite mineralization are direct prospecting marks， and also have obvious Au-Zn-Mo-W elements geochemical and remote sensing image anomalies in the mining area. The discovery of Tianyun gold deposit shows that the metallogenic geological conditions are superior to prospect in the Tianmu gold belt. |
