摘要
江西会昌密坑山中生代火山岩盆地是新近开发的重要锡多金属矿产区。本文首次确定本区为一发育完全的复活破火山口,在总结该区锡多金属矿化特征的基础上,通过资料分析,揭示出成矿作用与火山作用在时间、空间、物质来源等方面的内在联系,建立成矿模式,指明找矿方向,在理论和实践上具有一定意义。
The Sn-polymetal ore deposits located in the basin of Mesozoic volcanic rocks in the Mikengshan mountain area, Huichang, Jiangxi, are the main ones exploited recently. It is confirmed for the first time in this paper that the described area is well developed a revived caldera , by the analyses of all the macro-and micropic study data. bringing to light the relationships between mineralization and volcanism in time, space and source material. It is, consequently, of great importance theoretically and in practice to establish metallogenic model to guide the prospecting of such kind of ore deposits.
