| 摘 要： | 鹅公山火山盆地是赣杭构造火山岩带铀多金属矿产较丰富的火山盆地。在整理前人勘查成果资料的基础上,总结了铀、金、银成矿地质特征,从火山盆地成矿元素聚集、构造、岩浆活动、围岩蚀变、隐爆作用及幔源物质等方面对火山盆地铀多金属矿成矿条件进行了分析,认为中生代强烈的火山岩浆活动及其作用,为火山盆地火山—潜火山热液型铀多金属成矿提供了有利的地质条件。文章建议加强隐爆角砾岩与成矿关系及幔源物质参与成矿作用的研究。

| Abstract: | Egongshan volcanic basin which is rich in the uranium-polymetallic mineral in the Gan-Hang Tectonic volcanic belt. On the basis of collecting the previous exploration results,this paper has summarized the mineralization geological characteristics of uranium,gold and silver,analyzed the metallogenic conditions of Uraniumpolymetallic deposits in Volcanic Basin from Ore-forming elements gathering,structure,magmatic activity,wallrock alteration,cryptoexplosion and mantlederived material,etc. It is considered that the strong volcanic magma activity and function in Mesozoic has provided favorable basic geological conditions for the volcanic-cryptovolcanic hydrothermal Uranium-polymetallic deposits in the volcanic basin. It is suggested that study on the relationship between cryptoexplosive breccia and mineralization and whether the mantlederived material involves in the mineralization should be strengthened. |
