摘要
In this paper, the author carried out joints data measurements in the Meso-Cenozoic strata of Southwest Qaidam Basin, and then deduced the stress direction applying the strata recovery technique to different formations. The results suggest that the effect of Altyn Tagh fault to Southwest Qaidam Basin is difference in various periods, that is, it is very narrow just along Altyn Tagh Mountains during Late Cretaceous, while it enlarge gradually to Ganchaigou anticline and Youshashan anticline during the Eocene Shangganchaigou epoch and Miocene Xiayoushashan epoch for two stages of strike-slip and thrust movement of Altyn Tagh fault.
