湘南东坡矿田钨锡成矿系列硫同位素特征

Sulfur Isotope Characteristic of the W-Sn Metallogenic Series,Dongpo Orefield,Hunan

湘南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(由早至晚:γ_5^(2-1)→γ_5^(2-2)→γ_5^(2-3)→γπ)叠加于不同含矿建造上(岩浆岩、碎屑岩和碳酸盐岩)形成了不同类型矿床,主成矿元素呈现W、Sn→Sn、Cu→Pb、Zn的演化趋势,从而构成了东坡矿田W、Sn成矿系列,其硫同位素呈多峰分布,显示了多来源特征,并以千里山岩体为中心呈现规律性分布。

The Dongpo orefield, Hunan Province, is an important part of the south China Metallogenic Province. In the orefield, different ore-bearing igneous rocks superimpose different ore-formations, therefore, different types of ore fields formed. The main metallogenic elements changed from W, Sn to Sn, Cu and finally to Pb, Zn, forming the W-Sn metallogenic series. The sulfur isotope is of multi-peak that exhibits multi-resources.
