| 摘 要： | 小石头泉矿区主含矿层为下石炭统雅满苏组第二亚组，火山穹隆及伴生断裂为主要的控矿构造。矿区含矿火山岩组合属岛弧钙碱性－拉斑玄武岩系列，不具备形成火山成因的块状硫化物矿床的条件。小石头泉铜多金属矿床可归属为与次火山热液有关的脉状铜铅锌银多金属矿床，矿田矿化带规模宏大，具备形成大型矿床的地质条件，矿区外围中酸性侵入岩体具有形成斑岩铜矿的地质条件。 |
| 关 键 词： | 新疆 铜多金属矿床 地质特征 找矿前景 成矿作用 控矿构造 |

| Abstract: | Yamansu Formation of the Lower Carboniferous comprises the main ore-bearing formation in the Xiaoshitouquan ore district. The ore-controlling structural system of the Xiaoshitouquan copper and multi-metal orefield is mainly composed of volcanic dome with associated faults. Ore-bearing volcanic rock association is categorized into island arc calc-alkaline-tholeiite series, which is unfavorable for the formation of submarine volcanogenic massive sulfide deposits. So, the Xiaoshitouquan Cu-multimetal deposit is regarded as a subaerial sub-volcanic hydrothermal vein type of copper, lead, zinc and silver. It indicates that porphyry copper deposits should be exploited in the intermediate-acid intrusive rocks within the district. |
| Keywords: | Xinjiang Xiaoshitouquan Cu-multimetal deposit geological characteristics of ore deposit exploration prospect |
