| 摘 要： | 从川滇块体东缘的地质构造应力场、地震形变带所反映的构造应力场，震源机制解所确定的应力场、地壳应力解除及地壳应力测量所反映的应场等方面的资料，对场体东缘地壳动力学问题进行了讨论，结果认为印度板块与欧亚板块的碰撞是川 滇块体东缘地壳动力的主要力源。

CRUSTAL DYNAMICS DISCUSSION ABOUT THE EAST PART OF SICHUAN-YUNNAN BLOCK |

| Abstract: | According to several stress field figures obtained from geological tectonic analysis,deformation belts surveying,focal mechanism solution,crustal stress release method and crustal stress measurements,the whole geologic stress fields aroud the east part of Sichuan-Yunnan block is drawn out .Its crustal dynamics topics are discussed and the main source force comes from the collision between Indian plate and Eurasian plate. |
