| 摘 要： | 东腰庄金矿为五台山区典型的绿岩带型金矿,成群成带顺层展布于鸿门岩组中下部,具明显的层控特征.金矿化严格受台怀-李家庄同斜倒转复式向斜与李家庄-大草坪韧性剪切带控制,故其又是一个较典型的剪切带型金矿床.东腰庄金矿成矿作用具有多机制和多期性.成矿模式可概括为：火山-沉积-区域动力变形变质-褶皱转折端扩容成矿-韧性剪切带扩容成矿-改造叠加富集成矿.成矿作用主要发生在五台中期,并严格受该期形成的李家庄-大草坪韧性剪切带控制.主要控矿因素是矿源层、热动力和构造,其中构造是最主要的控矿因素.构造-变质热动力叠加改造的矿源层是最佳的成矿和找矿地区.

| Abstract: | Dongyaozhuang gold deposit is a typical greenstone belt gold deposit in the Wutai Mountain area. The deposit occurs as groups, belts and bedding developed in middle and lower parts of Hongmenyan Formation with distinct stratabound feature. Gold mineralizations are strictly controlled by Taihuai - Lijiazhuang homoclinal reversing compound synclinc and Lijiazhuang - Dacaoping ductile shear zone. Therefore it is also a typical of shear zone - type gold deposit. The gold mineralization is of multi - genesis and multi - period. The mineralization pattern can be concluded as volcano - sedimentation - regional dynamic deformation to metamorphism - fold twist crown dilation - ductile shear zone dilation - reformation and superimposition. The mineralization occurs mainly in middle Wutui stage and is strictly controlled by Lijiazhuaug - Dacaoping ductile shear zone that formed at that time. The main controlling factors are ore -bearing strata, thermal dynamic and structures, among them structures is the most controlling factor, Ore -beating strata reworked by structural and thermal dynamic are the best places for ore formation and ore prospecting. |
