Based on the field work data of fault plane scratch on Northern Margion Fault of Xinglongshan, Baiyangshugou fault and Xiwan-Leizhuang fault, the tectonic stress field is obtained. With other data related to the contemporary tectonic stress field, the characteristics of tectonic stress field in Lanzhou region are summarized: (1)The direction of the principal stress along the fault zone mainly varies with NNE-NEE. (2)The contemporary tectonic stress field inherites the one in Late Pleistocene. (3)The stress field on surface is concordant with that in depth. (4)The contemporary regional stress field mainly is in a horizontal compression way. |
