Cenozoic uplift, exhumation and deformation in the north Kuqa Depression, China as constrained by (U–Th)/He thermochronometry
Placing spatial and temporal constraints on deformation, uplift and exhumation using thermochronology methods can shed light on Cenozoic orogenic evolution in the Kuqa foreland. New apatite (U–Th)/He and previously published apatite fission track thermochronology are combined with vitrinite reflecta...

| description | Placing spatial and temporal constraints on deformation, uplift and exhumation using thermochronology methods can shed light on Cenozoic orogenic evolution in the Kuqa foreland. New apatite (U–Th)/He and previously published apatite fission track thermochronology are combined with vitrinite reflectance data and modeling to compile a low temperature, multi-stage thermal history of tectonic uplift/thrust and exhumation. A rapid uplift and exhumation event originated in South Tianshan during the Eocene (~ 46 Ma), with systematic younging of mean apatite (U–Th)/He ages from north to south (from the margin towards the interior). Uplift and exhumation south edge of the Biyoulebaoguzi anticline in the northern monocline belt at ~ 36 Ma with more than 3400 m of stratum denuded. Subsequently, deformation and uplift south edge of the Biyoulebaoguzi anticline in the northern monocline belt at ~ 36 Ma with more than 3400 m of stratum denuded. Subsequently, deformation and uplift extended to the northern edge of Kelasu–Yiqikelike at ~ 10 Ma and then at ~ 6 Ma, the Kanyaken anticline formed and uplifted resulting in 3000–3700 m of overburden erosion. The data support sequential southward propagating deformation and uplift (inferred exhumation) in the north Kuqa Depression during the Cenozoic, probably as a result of the collision of India with Asia far to the south of the Tianshan. |
