摘要: 大同火山群是我国东部重要独特地貌类型之一。火山群及其所在的大同盆地位于上地幔隆起带上,受中国东部最突出的构造地貌格局——NNE向雁行右旋剪切拉张断陷带控制。火山群及熔岩溢出带即明显沿着这个右旋剪切拉张破裂带以及与NW压扭性断裂交汇处发育,同时受到断裂多次活动的影响。

Abstract: The Datong volcano groups are one of the important specific landform types in the eastern part of China. The development of volcano groups and the Datong Basin Where the volcano groups are located and controlled by the most striking morphotectonic pattern in the eastern part of China-NNE-trending en echelon right-lateral shear-extensional down-faulted zone, located on the upper-mantle upheaval zone. The volcano groups and lava flows are developed obviously along the NE-trending right-lateral shear-extensional fracture zones and their intersection with NW-trending shear-comprcssional faults, and also continuously affected ty re-activation of faults.
