| Abstract: | In this paper, in was described that the tectonic deformation of the Changyuan Granitoid Complex and its wall rocks, which are exposed in the northem part of Beijing Municipality. The onigin of the defomation was also discussed. We proposed that the change of tectonic stress field during Middlle and Late Jurassic period is the main factor to cause the variation of deformational pattem among the plutons in Changyuan Granitoid complex. |
