摘　　要：东坡矿田是华南成矿区的重要组成部分 ,区内不同的含矿岩浆岩叠加于不同类型的含矿建造之上 ,形成了不同类型的矿床和W、Sn成矿系列。从早到晚 ,含矿流体从富岩浆水→富大气降水 ,伴随这一演化趋势 ,主成矿元素从W、Sn→Sn、Cu→Pb、Zn。从而形成了东坡矿田W Sn成矿系列。Dongpo ore field is an important part of Hunan metallogenetic area. In the area, different ore-bearing magma were superimposed over different ore-formation, and came into being various types of deposits and W-Sn metallogenic series.From early time to late time , the fluid changed from magmatic water to richness in atmospheric water. With the variation of this evolution, the main ore-forming elements change from W, Sn to Sn, Cu and eventually to Pb, Zn. Therefor W,Sn metallogenic series is formed in the Dongpo ore field.
