| 摘 要： | 新甸金矿的形成受构造活动的控制非常明显。辽河群盖县组的形成，为本区金矿的形成准备了物质基础。随着区域构造活动的发展，盖县组发生变形变质作用，使岩层中的物质组分变质分异形成硅化石英脉，这一过程是金矿物质的初次迁移和聚集，也是本区金成矿作用的前期准备阶段。后来变质岩系交代重熔形成似斑状黑云母花岗岩，促使大量的成矿物质聚集到岩浆期后热液中。含矿热液沿剪切构造裂隙充填形成了一系列金矿脉、金矿体。剪切构造活动期次与金成矿作用期次有对应关系。剪切构造是矿脉、矿体空间展布、定位的主要控制因素。

| Abstract: | The gold mineralization of Xindian gold deposit are very distinctly controlled by struc-ture activities． Gaixian formation of Liaohe group offered the base of mineralised material forthe gold deposit． Following metamorphism caused by motive force of the metamorphisedrocks of Gaixian formation，the material in rocks occurred differentiation and formed silicifiedquartz veins. In this process,the mineralization material are firstly migrated andriched． Afterly，the metamorphised rocks are metasomated and resoulted，and formed porphy-roid biotite－granite. In the post－magmatic hydrothermal， a great quantity mineralizationmaterial are riched． The hydrothermal riched mineral filled shear structure and formed a largenumber veins or bodies，The stage of shearing contrast with the stage of mineralization. Shearstructure is a factor controlled veins and sites and shape of the bodies. |
