Summary
Travertine deposition in the Dawan Valley, adjacent to China's Huanglong World Heritage Site, began around 13,000 years ago and declined by 7,000 years ago. This timing coincides with large-scale travertine deposition in the nearby Huanglong Valley, suggesting a hydrological transition event linked to tectonic activity, earthquakes, or glacial retreat due to climate warming. Using U-series dating via multi-collector inductively coupled plasma mass spectrometry, researchers established a time series for travertine formation, providing critical age data for late Cenozoic geological and environmental events on the eastern Qinghai-Tibet Plateau. The study offers new insights into glaciation, tectonic activity, and seismicity but highlights the need for further exploration of depositional breaks and forcing factors.
