The kinematic characteristics and dynamic mechanisms of key faults in the Yinggehai Basin and the Red River Fault Zone remain controversial.This study applies stratigraphic backstripping and balanced cross -section restoration to quantify subsidence and extensional rates of major faults in the Yinggehai Basin across different geological periods, aiming to clarify the tectonic activity of the Red River Fault Zone and the basin′s evolutionary history.Results show that between 30 and 21 Ma, strikeslip faulting was primarily concentrated along the Song Lo Fault, while horizontal extension remained relatively minor.During this 基金项目： 国家自然科学基金联合基金项目(No.U19B2007);国家自然科学基金面上项目 (Nos.42072142,42172182).
