【摘要】 东川矿区播卡地区小溜口组金矿的发现为矿区昆阳群的找矿工作开拓了新的找矿思路。通过研究小溜口组金矿化特征、载金矿物黄铁矿特征、金赋存状态等特征,初步提出本区金矿化与穆龙套金矿床特征相类似,属于黑色岩系金矿的思路,认为在滇中地区昆阳群钠质火山岩、黑色碳硅质页岩系中进行金矿找矿有巨大潜力。更多还原

【Abstract】 The discovery of gold mineralization in the Xiaoliukou Formation in the Boka-Tuoboka area of the Dongchuan district has provided a new ore-search idea for the follow-up exploration in the existing mining area of the Dongchuan copper mine. This paper has focused on the features of gold mineralization in the Xiaoliukou Formation, gold-bearing pyrite and gold occurrence in ore. It is preliminarily concluded that the gold mineralization in the Dongchuan area shares much in common with that of the Muruntau gold deposit in Uzbekistan. The gold mineralization genetically belongs to the black shale series ore deposits. It is suggested that there is a higher potential for gold prospecting across the distribution area of the black shale and albitite rocks of the Proterozoic Kunyang Group in central Yunnan Province.更多还原
