摘　　要：东坡矿田所处湘南区域,岩浆岩比较发育,由老到新依次为花岗岩、花岗斑岩脉、辉绿玢岩脉,主要分燕山早期和晚期两期五次侵入就位。在统计前人所做的K-Ar、Rb-Sr同位素测定的基础上,笔者对各期依次所形成的主要矿体特征进行总结概述。The Dongpo orefield is located in south Hunan characterized by widely exposed magmatic rocks such as granite, granite porphyry dykes and allgovite dykes which were emplaced in early and late Yanshanian Epoch. This paper has a discussion on geological features of the main orebodies based on existing K-Ar and Rb-Sr isotope geochemical data.
