Abstract: In Daheshang mountain and adjacent area occurs an upper interlayer (or cover) gliding belt consisting of a series of imbricate overthrust faults, at their base exists a large main thrust withalow dip angle, occurring between the overlying soft cover and the underlying rigid rock basement. The gliding motion along this main thrust caused the geological structures to be formed between the cover and basement. But they differ from the structures formed in Pre-Sinian basement. The formation of this structural system in studied area can be considered as a reault of lateral compression in SEE and NWW directions. And the cover gliding probably started from Late Paleozoic and continued in Jurassic period or later.
