摘要
The Tianshan Mountains is characteristic of a typical intracontinental activity. In order to help decipher the actual structural interpretation of the south Junggar Basin and the styles of deformation, we measured strikes and dips of strata at every spot in detail by the use of 200 m-long lining rope or GPS along a 50 km section at the Jinggou River (Xinjiang Province) in the year 2005, and regional field survey for many years after 2005. Based on the times of three main folds, we conclude that the south Junggar fault and fold belt is of a break-back thrust sequence (new thrusts developed in the hangingwall), still being active from the early quaternary to present.
