Based on a large number of tectonic trace measurements and analysis of the western Hunan and Hubei tectonic belt, this study is a statistical analysis of tectonic deformation age data in the study area. It is clear that the early arc structure of the mid- Yanshan (J3—K1) has a top direction of 330° and diverges on both sides, with Dabie Mountain, central Guizhou and Huangling uplifts as the restraining points, and the western Hunan and Hubei formed arc structure from the southeast to the northeast whose construction trace gradually deflected from NE→NEE→EW→NWW, and the direction of the maximum principal stress deflected nearly 114°. At the same time, during the early expansion of the arc structure, near SN directions (the Daershan- Chayuan and the Wujiang- Daqian faults) and NW strike- slip fault (the Xiannvshan fault) were formed on both wings of the arc structure; the arc top direction of the late- arc structure developed in the late Yanshan (K1—K2) is 296°. Due to the influence of the Qiyueshan fault, the late arc- shaped structure is divided into two stages, the late K1 phase (the first period of arc structure in the late Yanshan), and K2 (the second period of arc structure in the late Yanshan). Taking the Daba Mountain, Central Guizhou and Huangling uplifts as restraining points, the western Hunan and Hubei formed an arc structure from the southeast to the northeast with construction trace deflected from SN to NE, the direction of the maximum principal stress deflected nearly 86° and gradually extended to the Sichuan Basin until the Huaying Mountain fault. There is a certain difference in the impact intensity range of the two- stage arc structure. The northeast side of the study area is dominated by the mid- Yanshan arc structure, and the southwest side is dominated by the late Yanshan arc structure, resulting in differences of oil and gas reservoir between the northeast and southwest of the western Hunan and Hubei.
