The Northeastern part of the present-day Qinghai-Tibet region had a higher elevation than the Southwestern part until the earliest Miocene, i.e., circa 23 million years ago. Thereafter, two phases (12-8 and 5 million years ago) of intensive differential tectonic uplifting led to a significant geomorphologic reversal, resulting in the Southwest/Northeast tilting of the Qinghai-Tibet Plateau as seen today.
