湖南省界牌岭锡多金属矿床地质特征研究

Geological Characteristics of Stannum Polymetallic Deposit at Jiepailing in Hunan Province

界牌岭锡多金属矿床之萤石、铍、锡、铜等矿化与云母萤石化、黄玉萤石化蚀变的时空关系密切,燕山晚期复式小岩体与含矿流体是深部岩浆不同时期分异产物。文章通过对矿床蚀变、矿化分带、矿石特征、可选性试验、成矿地质条件、成矿物质来源等进行分析,建立矿床的成矿模式,指出找矿预测区。

For Jiepailing stannum polymetallic deposit, there is a pretty close spatio-temporal relationship between the mineralization of fluorite, beryllium, stannum and copper and the fluoritization of mica, fluoritization-alteration oftopaz. The small composite intrusive rocks and ore-bearing fluids of late Yanshan period are originated from deep magrnatic differentiation at different ages. Based on the analyses of alteration zoning, mineralization zoning, ore characteristics, processibility experiment, ore-forming geologic conditions and ore matter sources of the deposit, metalloganic model of the deposit is established, and prospecting prediction areas are proposed.
