According to field seismo-geological investigation and fault slip observation, the active faults in northeast direction in ace w:st="on">aceName w:st="on">Yanfan aceName> aceType w:st="on">Basin aceType> ace> are mainly dextral strike-slip, with some cases of normal fault. But in ace w:st="on">aceName w:st="on">Huaizhuo aceName> aceType w:st="on">Basin aceType> ace>, the situation is opposite; the active faults in northeast direction are mainly normal faults, with some cases of strike slip. However, in the whole ace w:st="on">aceName w:st="on">Yanhuai aceName> aceType w:st="on">Basin aceType> ace>, the active faults in northwest direction are mostly sinistral strike-slip, also with some cases of normal fault. By field investigation and observation, the authors got 337 data of active fault slickenside. And using the method of inversion of fault slip data, the authors can obtain the following characteristics of recent tectonic stress field in the research region.
