| 摘 要： | 大同-阳原盆地的形成演变研究表明，本区最早出现的是将军庙盆地，依次是大同盆地、阳原盆地，直到第三纪末至早更新世初才出现统一的大同-阳原古湖。大同-阳原古湖历时二百余万年，至晚更新世末消亡。新生代以来，大同-阳原盆地火山活动频繁，新构造运动活跃，现在仍是地震灾害的危险区之一。

| Abstract: | Study on formation and evolution of the Datong Yangyuan basin reveals that the earliest basin appeared in the region was the Jiangjunmiao basin, then the Datong basin, and the Yangyuan basin. The ancient Datong Yangyuan lake did not appear until the end of the Tertiary and the beginning of the Early Pleistocene. This lake lasted about two millions years and vanished in the Late Pleistocene. Since the Cenozoic this region has experienced frequent volcanism and active tectonism. Several times of stronger earthquake have happened in recent decades. |
