| 中文摘要:彩虹铜多金属矿床位于库米什-彩华沟-依格尔达坂多金属成矿带内，具多期成矿特征。早期的火山_沉积成矿作用形成了层状含铜黄铁矿层。第2期热液成矿作用形成了脉状、块状、团块状的铜（铅锌）矿化，氧、氢同位素及流体包裹体研究均显示，在该期矿化过程中，有岩浆流体的参与，结合钨异常及时间证据，认为该期矿化与忠宝岩体的侵入有关，且受NE向构造的控制。成矿物质来自围岩阿尔彼什麦布拉克组。矿床成因为火山沉积-岩浆热液叠加改造型。 |

| Abstract:The Caihong Cu-polymetallic deposit located in the Kumux-Caihuagou-Yigeerdaban polymetallic ore belt is characterized by multi-stage mineralization. The early volcano-sedimentary metallization formed copper-bearing pyrite bed, and the late hydrothermal mineralization formed veinlike, stockwork or massive copper-lead-zinc ore, controlled by NE-trending structures. Magmatic fluid participated in mineralization of this stage, as shown by O-H isotope and fluid inclusion studies. In combination with tungsten anomaly and time evidence, the authors hold that hydrothermal mineralization was related to Zhongbao granite, whose intrusion occurred in Hercynian period. Ore-forming material probably came from the wall rock. The Caihong ore deposit is genetically of the volcanogene sedimentary-magmatic hydrothermal superposition and reformation type. |
