| 摘 要： | 广西大厂锡矿黑水沟矿体赋矿层位中发现的中基性火山岩主要为玄武岩、安山岩类岩石,大都属于钙碱性-碱性系列。岩石地球化学特征表明该火山岩可能形成于裂谷环境。在大厂矿区,除了存在传统的燕山晚期花岗岩成矿作用外,至少还存在海西早期海底基性火山－沉积成矿作用和海底喷流热水－沉积成矿作用。

| Abstract: | The intermediate-basic volcanic rock in Dachang Heishuigou area of Guangxi is basalt and andesite rocks, mostly of which belong to sub-alkaline basalt series and a flow basic series. The geochemistry characteristics indicate that the volcanic rocks maybe formed in an island-arc environment. In Dachang area, traditional granite mineralization occur in late-Yanshanian period, and the mafic submarine volcanic and sedimentary-exhalative mineralization and submarine exhalative hot water - the role of sedimentary mineralization occur in the early Hercynian period. |
