A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.
