Abstract Based on remote sensing interpretation, field investigation, optically simulated luminescence(OSL) dating and UAV topographic mapping, we carry out a preliminary study on the development characteristics and deformation of river terraces in Tongcheng-Taihu section at the eastern foot of Dabie mountain. The results show: 1) The river terraces in the eastern foot of Dabie mountain are poorly developed; the first-class terraces are generally developed in small and medium-sized rivers, and the second-class terraces are developed in a few large rivers. 2) The formation age of T1 terrace of the river in the eastern foot of Dabie mountain is from the late Pleistocene to the early Holocene(about 25 ka BP~12 ka BP), and the formation age of T2 terrace is the middle of late Pleistocene(about 55 ka BP). 3) There has been no obvious activity at the eastern foot of Dabie mountain of Tanlu fault zone since the formation of T2 terrace of the river. The latest active age of the fault in this section is the middle Pleistocene.
