| 摘 要： | 燕辽地区位于华北地台北缘东段，是我国著名的中生代火山热液型铀、金、多金属矿床成矿区。研究结果表明，其成矿作用受统一的晚中生代大陆裂陷火山岩浆活动控制；成矿时代集中在晚侏罗世及早白垩世；成矿介质为火山岩浆水、变质水和大气水混合的中温、中低温火山热液；成矿物质主要来自富集型的上地幔及下地壳。

| 关 键 词： | 燕辽成矿区，铀－金－多金属矿床，中低温火山热液 |

| Abstract: | Yanshan-Liaoning area is located in the east part of the northern margin of the north Chinaplatform. It is a famous metallogenic region of Mesozoic volcanic hydrothermal type U-An-polymetallic deposits in China. Research achievements indicate that the metallogenesis in the region iscontrolled by a united Late Mesozoic continental taphrogenic volcano-magmatic activity; the metallogenic epoches are concentrated in Late Jurassic and Early Cretaceous periods; the metallogenicmedia are moderate and moderate-low temperature volcanic hydrothermal solutions originatedfrom the mising of volcano-magmatic water, metamorphic water and atomspheric water; theore-forming materials are mainly derived from enrichment type upper mantle and lower crust. |
