摘要

In thisp aper, the authors identified Derbugan fault with the characteristics of southeast direction dip and cutting lower crust. Combining with the study of the measured geological section and the microstructure, it is considered that tectonic attribute of the Derbugan fault is not the matching belt between massif and massif, orogenic belt and orogenic belt in different periods, but it is a NE extending, large-scale extensional deformation zone cutting lower crust in Late Jurassic-Early Cretaceous. And it is also the boundary fault zone of control basin between the uplift region and the basin in Genhe, Labudalin and Hailar in Late Mesozoic era.
