Cenozoic tectono-geomorphic growth processes of the Yabrai Fault (YBF) along Yabrai Mountain (YM) and their impacts on the landscape formation of Badain Jaran Desert (BJD) during the late Quaternary are still unsolved, and yet are crucial to exploring the tectonic evolution of the boundary between the northeastern Tibetan Plateau and southern Gobi Alxa block. This study addresses these issues using information extraction-based interpretations of multiple satellite images coupled with field observations. The 138 km-long NE-NEE striking YBF can be divided into 3 segments: southwestern, central, and northeastern segments all characterized by left-lateral faulting with normal faulting components. Apatite (U-Th)/He thermochronology and calcite (U-Th) dating integrated with regional tectonic evolution history provides new geochronological evidence for understanding the multi-stage evolution of the YM and YBF. (1) Before the late Cretaceous (135–72 Ma), the mountain experienced rapid cooling and uplift. (2) During the late Cretaceous to Eocene (ca. 70–33.9), the YM is likely to have experienced denudation and flattening. (3) From the Oligocene to early Pliocene (33.9–5 Ma), the YBF underwent ~47 km of left-lateral displacement that accommodated the slip of Altyn Tagh Fault (ATF). (4) Since the Pliocene (5 ± 1 Ma), the YBF is characterized by left-lateral strike-slip faulting with a normal faulting component. The normal faulting resulted in uplift and the creation of topography along the central segment of the YBF. This has impeded the southeastward migration of sand dunes, building the world's highest megadune within the BJD. The tectono-geomorphic growth of the YM and YBF plays a key role in formation of the unique megadune-lake pattern and in preventing the merging of the BJD and Tengger Desert (TD).

亚布雷山（YM）沿线的亚布雷断裂（YBF）的新生代构造地貌生长过程及其对晚第四纪巴丹吉林沙漠（BJD）景观形成的影响尚未解决，但对于探索构造演化至关重要青藏高原东北部与戈壁阿拉善地块南部交界处。本研究使用基于信息提取的多卫星图像解释和实地观察来解决这些问题。长 138 km 的 NE-NEE 走向 YBF 可分为 3 个段：西南段、中部和东北段，均以左侧断层为特征，断层成分正。磷灰石（U-Th）/He热年代学和方解石（U-Th）测年结合区域构造演化史，为理解黄颡顼和黄骅BF多阶段演化提供了新的年代学证据。(1) 晚白垩世（135-72 Ma）之前，该山经历了快速冷却和隆升。(2) 晚白垩世至始新世（约 70-33.9），YM 可能经历了剥蚀和变平。(3) 从渐新世到上新世早期 (33.9-5 Ma)，YBF 经历了约 47 km 的左侧位移，以适应阿尔金断层 (ATF) 的滑动。(4) 上新世以来(5±1 Ma)，YBF 以左旋走滑断层为特征，断层为正断成分。正断层导致沿 YBF 中部的隆升和地形的形成。这阻碍了沙丘向东南迁移，在 BJD 内建造了世界上最高的巨型沙丘。YM和YBF的构造地貌生长在形成独特的巨沙湖格局和阻止BJD与腾格里沙漠（TD）合并方面起着关键作用。
