| 摘 要： | 华北地台北缘中段中上志留统与中元古代自乃庙群接触关系为角度不整合,且沿角度不整合面发生了构造叠加作用,产生了滑断构造。该滑断构造具有宏观、微观变形组构,并且控制了一系列金矿点(矿化点)的分布,是一条重要的金矿化带。

| Abstract: | The contact relation between the Middle-Upper silurian on the centra part of the northern margin of North China platform and the Bainaimiao Group is angular discordance. The tectonic overlap is along the angular disordance plane, forming slip-fault structures with macroscopic and microcosmic deformation fabric, which govern the distribution of a series of gold spots (mineralized spots), forming an important gold mineralized belt. |
