【摘要】 金等微量元素的地球化学研究表明。醴陵雁林寺金矿床成矿物质主要来源于中元古界冷家群浅变质浊积岩系。金矿化可划分为两期:第1成矿期,成矿流体可能为区域变质作用形成的变质热液;第Ⅱ成矿期,成矿流体应为韧性剪切作用形成的动力变质热液(局部地段为岩浆热液)。储矿环境为弱碱性弱还原环境。矿床具多因复成特征。更多还原

【Abstract】 Geochemical study of Au and other trace elements shows that metallogenic material of Yanlingshi gold deposit in Liling Comes from lowrank metamorphous turbidite system of mid—proterozoic Lenjiaxi group. Mineralization of Au can be divided into two periods. During the 1st period the metallogenic solution may be meta-morphous. which is formed by the regional metamorphism and during the 2nd period the metallogenic solution should be dynamic metamorphous(magmatic in some parts), which is formed by the ductile shearing. The proper-ties of these two solutions, slightly alkline and weakly reducing, is the favourable condition for the ore precipita-tion. According to the point of view of author the deposit is characterized by multi—genesis.更多还原
