吉林省东南部金矿成矿条件及找矿靶区预测研究

Study on prognosis of metallogenic conditions and ore finding target area in the southeastern part of Jilin Province

吉林省东南部可划分为台隆型、褶皱带型、槽台过渡带型等三类金矿化域，对变质建造、沉积建造和岩浆建造的岩石地球化学特征，Ｐｂ、Ｓ同位素，稀土元素特征进行了分析和讨论，阐述了金元素在不同含矿建造中的成矿作用及地球化学特征，并对全区进行１∶２０万区域成矿预测，对重点靶区进行了大比例尺成矿预测，指出了找矿方向及强蚀变岩型及浸染型金矿的找矿工作。

In this paper,the southeastern part of Jilin Province are divided into three type gold metallogenic district , i.e.platform type ,folded belt type and trough plat form transition belt type .the characteristics of rock geochemistry of the metamorphic formation,sedimentary formation,magma formation,isotopes of Pb and S and rare earth element are analysed and discussed.The metallogenesis of gold element in different ore bearing formation and its geochemical characteristics are described .In addition,the 1/200,000 regional metallogenic prognosis of the whole region is made and the large scale metallogenic prognosis in the main target area are made too.Simultaneously,the ore finding orientation and work of intensely altered rock type and gold deposit of dissemination type are put forward.
