Paleomagnetic study was carried out with the 96 samples (from 12 sites) collected from the Cretaceous red sandstone strata on the two wings of the Dadeli syncline, southwest of Xichang, in the Sichuan_Yunnan rhomboidal block.

Structural Transformation and Strain Partitioning along the Northeast Boundary Belt of the Sichuan-Yunnan Block;

With the measuring technology of photogrammetry and chronological method of analysis among regional climate,geomorphology and tectonics,we get a set of quantitative kinematical data for the main faults along the northern-eastern active boundary belt of Sichuan-Yunnan block.

Numerical simulation of loading/unloading effect on Coulomb failure stress among strong earthquakes in Sichuan-Yunnan area;

Simultaneous inversion of small earthquake relocation and velocity structure in Sichuan-Yunnan area;

On the basis of the analysis of velocity field,deformation field and strain field of Sichuan-Yunnan area,we proposed the complex deformation model with coexistence of clockwise rotation around eastern Himalayan syntaxis,stretch,compress and shear deformation in Sichuan-Yunnan area.
