The Altyn Tagh fault has been a crucial tectonic boundary of the Tibetan Plateau during Cenozoic India-Eurasia collision. However, issues have not addressed regarding evolution kinematic transformation from eastern to Qilian Shan. Here we focus on kinematics at point, Subei triple junction, along fault, which was recorded by faulting in Suganhu basin south junction. We reconstructed structural pattern faults and thickness distribution strata integrating seismic profiles, well logging, topographic data. inferred that only crustal shortening thickening Danghenan Shan, prominent high, absorbed strike-slip displacement early Cenozoic. Since mid-Miocene, belts within were initiated, based geometry uneven across belts. thus proposed mid-Miocene realized blocks extruding southeastward, as entire Those are bounded preexisting weaknesses with lateral movements, lithospheric heterogeneity played an essential role block-scale extrusion.

Abstract The Cenozoic topographic growth of the Tibetan Plateau is a pulsed, polyphase process that still requires more constraints. sedimentary record Ningnan Basin, continental basin located adjacent to northeastern margin Plateau, key archive for recording surface evolution Plateau. This work reports new provenance data (apatite fission‐track, apatite U–Pb dating, and trace element analysis on same individual grains) from Oligocene–Pliocene sequence filled Basin. set shows variations in patterns through Miocene which are related tectonic In contrast primary Western Ordos Block (WOB) during Oligocene, sediments were mostly derived recycling Mesozoic successions occur along northwestern Haiyuan Fault, documenting it was active last ca. 15 Myr. These sediments, turn, different orogenic blocks but mainly segments Qilian Mountains. We show Late Miocene–Pliocene primarily transpressional uplift affected regions such as Liupan Progressive northeastward migration stress since Middle has induced extensive regional deformation particularly Fault. neighbouring basins deciphering this evolution.
