Based on the previous studies, structural transfer zones can be divided into two types: transfer zone and accommodation zone, between which there are significant differences in the aspects of stress mechanism, structural pattern and development position. This study focuses on three large structural transfer zones of Wuerxun Depression: Tongbomiao structural belt, Bayantala structural belt and Surennuoer structural belt. The basic theory of structural transfer zone combined with seismic data is applied to analyze the structural characteristics of Wuerxun Depression. The result shows that there are obvious differences among Tongbomiao structural belt, Bayantala structural belt and Surennuoer structural belt in the aspects of structural characteristics, plane fracture characteristics and profile evolution. And it is believed that Tongbomiao structural belt is accommodation zone, while Surennuoer structural belt and Bayantala structural belt are transfer zones.
