摘　　要：运用历史地质学观点,对吉林东部会全栈古穹窿构造格架的偏转变位等进行分析阐述;综合穹窿南东缘金矿地质特征,厘定出五台期和印支—燕山期为两个成矿期;初步探讨了各成矿期金成矿的基本地质条件;提出在三道溜河TTG岩石组合就位固结之后,钾质系列花岗岩浆冷凝之前为主成矿幕的观点,总结出该幕的综合控矿因素和地质找矿标志。In this paper,partial tranformation of Huiquanzhan ancient vault tectonic framwork on east of Jilin was set forth by the history geology viewpoint. The five and Indo-China-Yanshanian for the two ore-forming period was set out with integrating the geological characteristics of southeast edge gold mineralization,and the basic geological conditions of per mineralization period were preliminary studied. The viewpoint was put forword that the postassic granitic magma was main ore-forming screen before it condensated,and after three slide River TTG rock combo consolidated. The screen integrated ore-controlling factors and geological prospecting criteria were summed up.
