💰 Awarded Funding
NSF (NSF-42102023): Magnetostratigraphy study of the Eocene-Oligocene climate transition event in the Hoh Xil Basin, Tibetan Plateau. PI: Li Leyi. ￥300,000 (2022.01-2024.12). Open Fund of Yunnan Key Laboratory of Earth System Science (ESS2022001): Magnetostratigraphy of the Tuotuohe Formation in the Hoh Xil Basin, Tibetan Plateau. PI: Li Leyi. ￥30,000 (2023.1-2024.12).
📚 Academic Achievements
Stratigraphy and Age Control: Utilized seven methods including high-resolution magnetostratigraphy, biostratigraphy, and detrital zircon chronology to determine the depositional age of Cenozoic strata in the Hoh Xil Basin. Defined age ranges: Tuotuohe Formation (37-32.7 Ma), Yaxicuo Formation (32.7-23.6 Ma), Wudaoliang Formation (23.6-19.7 Ma). Palaeoelevation Reconstruction: Reconstructed palaeoelevation of Hoh Xil Basin at 29 Ma (2.5 km ± 0.5 km) and proposed a two-stage uplift model since the Eocene. Detrital Zircon Age Spectra: Indicated no significant change in provenance since the Late Cretaceous. Identified Tanggula Mountains as the main source area, with basin-mountain geomorphology established by the Late Cretaceous. Oxygen Isotopes and Climate Change: Identified a significant positive oxygen isotope bias at 30.5 Ma. Suggested this was due to Indian monsoon intrusion and increased evaporation linked to tectonic uplift.
🧪 Contribution to Research & Development
High-Resolution Chronological Framework: Constructed a detailed stratigraphic chronological framework for the Hoh Xil Basin, aiding future paleo-environment and tectonics research. Extended Indian Monsoon History: Provided evidence for the intrusion of the Indian monsoon into the central Tibetan Plateau at 30.5 Ma. Paleo-Elevation Insights: Demonstrated that the central northern part of the Tibetan Plateau was not at its current elevation in the Early Oligocene. Proposed a two-stage uplift model since the Late Eocene with corresponding dynamic mechanisms.
