摘要
东川拖布卡-布卡地区发现的独立型金矿是滇中昆阳群找矿工作取得的重大进展之一。金矿容矿地层-岔河组和清水沟组形成于昆阳裂陷槽演化的晚阶段。矿化类型有接触破碎带型和层控型金矿两种，其中，层控型金矿是本区主要的成矿类型。基于成矿控制因素的综合讨论，对区域性找矿意义进行了分析。
The discovery of gold ore deposits in the Tuobuka－ Buka area is one of the very important advances made in the Kunyang Group for ore－ prospecting.The ore－ bearing strata,Chahuo Formation and Qingshuigou Formation, were formed in the late stage of the evolution of the Kunyang taphrogeosycline.Gold mineralization in the area may be divided into two types:contact fractured zone type and strata－ bound type.The latter is the main mineralization type in the area. Based on the complex analyses of the gold ore－ con...
