Based on the detailed results of field survey, section mapping, and Quaternary dating data, the Late Quaternary activity characteristics of four major faults, i.e., the new Taoyuan fault, Daoguo fault, Hejiangcun fault, and the known Longpan-Qiaohou fault in the Taoyuan segment of Longpan-Qiaohou fault zone were studied. The results show that the activity characteristics of the Taoyuan section of Longpan-Qiaohou fault zone in Late Quaternary are obvious and the activity intensity is medium. The Longpan-Qiaohou fault and Hejiangcun fault are Holocene active faults, while the Taoyuan fault and Daoguo fault are Late Pleistocene faults. Since the Late Pleistocene, the Longpan-Qiaohou fault and Daoguo fault are dominated by left-lateral strike-slip, while the Taoyuan fault and Hejiangcun fault are dominated by normal strike-slip. The activity of these faults affects the seismic risk and tectonic stability of the study area and its vicinity to varying degrees. The research results in this paper provide the new data for further understanding the Late Quaternary activity of the Taoyuan segment of Longpan-Qiaohou fault zone, and can also provide basic geological data for further understanding the seismic geological characteristics and seismic safety evaluation of engineering construction in the study area.
