| 摘 要： | 在白垩纪和第三纪构造盘地基础上形成的商州第四纪盆地内，新构造断裂活动可分为早更新世末期平缓褶皱及与之相伴的压性断裂和中更新世末期张性断裂。该盆地属一北浅南深的掀斜断块，除北界外，南、西和东界均具断裂特点，其形成经历了挤压和引张两个阶段。

| Abstract: | The neotectonism in the Quaternary period basin of Shangzhou which forms in structural basin of the Cretaceous and Tertiary Period can be divided two kinds of groups, i. e.gentle fold of last phase in Early Pliestocene Epoch and compressional fracture associated with the gentle fold, and tensional fracture formed in end of Middle Pliestocene Epoch. The basin belongs to a tilted fault block that is shallow in the north and is deep in the south Southern, Western and eastern boundary of the tilted fault block are characterized by the fracture except for northern boundary. The formation of the tilted fault block is underwent two stages, that is to say, compression and extension |
