黔东同古金矿床地质特征及其成因探讨

同古金矿已有较长的民采历史。本研究在前人工作的基础上．结合开采揭车出的地质现象，从地层、构造、石英脉地质特征、矿石组分、金的富集和产出特征、成矿温度，矿床成因等方面对该金矿的地质特征进行了较全面的研究，特别是对以往工作没有揭露但对矿床有着重要控制作用的、新发现的剪切破碎带Fx进行了详细的研究，并指出了进一步找矿的方向。本研究成果对该地区寻找同类型金矿和新的富矿体将起重要作用。

GEOLOGICAL FEATURES AND GENESIS OF THE TONGGU DEPOSIT IN EASTERN GUIZHOU-A DISCUSSION

The Tonggu gold deposit has a long history of non-governmental exploitation and its research level is lower. This paper considered that the shear broken zone has an important controlling effect on the ore-forming process. This paper also probes into the geological features of the gold deposit. This study is of significance in searching for rich orebodies and gold deposits of the same type in this region.
