Did the growth of Tibetan topography control the locus and evolution of Tien Shan mountain building?

A new study suggests that the growth of Tibetan topography played a critical role in shaping the locus and evolution of mountain building in the Tien Shan, a significant intraplate mountain range in Central Asia. The research proposes that bending stresses from lithospheric flexure in Central Asia exerted a strong influence on the regional stress field, leading to increased compressive stress near the Tien Shan and reduced likelihood of mountain building south of it. This finding challenges the traditional hypothesis linking Tien Shan mountain building solely to the India-Eurasia collision and highlights the importance of bending stresses in propagating deformation into continental interiors. The study utilized models of Paleogene to Middle Miocene flexure to demonstrate this mechanism, offering a viable explanation for the synchronization of mountain-building events between Tibet and the Tien Shan.
