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。
The formation of Xindian gold deposit is controlled by tectonic activity. The formation of the Gaxian Formation in Liaohe Group provides a material basis for the formation of gold deposits in the area. With the development of regional tectonic activities, the Gexian Formation undergoes metamorphism and metamorphism, causing metamorphism and differentiation of the material components in the formations to form silicified quartz veins. This process is the first migration and accumulation of gold minerals and is also a gold mineralization in this area The pre-preparation stage. Later metamorphic metamorphic rock metamorphism to form porphyritic biotite granite, prompting a large number of ore-forming materials gathered in the magmatic hydrothermal. The ore-bearing hydrothermal fluids form a series of gold veins and gold ore bodies along the shear structure fissures. There is a corresponding relationship between the period of shear tectonic activity and the period of gold mineralization. Shear structure is the main control factor of ore veins, ore body space distribution and positioning.
