Correlation of Seismicity in Sichuan-Yunnan Rhombic Block;

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.

Aim A good number of Chuandianella ovata fossils from the Lower Cambrian, Chengjiang Lagersttte are examined herein.

In recent years,a number of Chuandianella ovata(an arthropod)specimens have been excavated from the Yu anshan Formation of the Lower Cambrian(the strata Chengjiang biota being excavated)in Haikou area near Kunming City.
