| Abstract: | The existence of the Yanyuan Lijiang block and its boundary are dicided and described in this paper.On the basis of remote sensing image and other data the strong seismicity and tectonic movement are discussed.The authors suggest that the generation of the Yanyuan Lijiang and Chuandian crustal blocks and their moving tendency should be resulted from the northward movement of the India plate and its indentation into Eurasia plate and the squeeze by the two plates,then they froce the earth substance in between to move(flow)eastwards,eastsouthwards and westsouthwards. |

| Keywords: | Yanyuan Lijiang block block movement squeeze out of earth substance |
