英文摘要 | Constraining the uplift of the northeastern Tibetan Plateau (NETP) is critical for growth models of the plateau and tectonic-climatic interactions during the Cenozoic. The sequence of early Eocene (53 Ma)-early Miocene (16 Ma) clastic sediments deposited in the Xining Basin provides insights into the uplift of the NETP. We used Nd-Pb isotopic composition of the Cenozoic sediments in the Xining Basin to trace sediment sources and hence to infer uplift of the NETP. Provenance analysis indicates that the Qilian Shan was possibly the source area before similar to 50 Ma; the West Qinling became the main source area during similar to 50-39 Ma; and the West Qinling, Qilian Shan, and Laji Shan probably became source areas during similar to 39-30 Ma. During similar to 30-16 Ma, the sediments comprised a two-end-member mixture of detrital materials from the Laji Shan and the Qilian Shan, whereas detrital inputs from the Qilian Shan increased after similar to 22 Ma. Combined with previous studies, our inferred provenance history suggests that (1) part of the Qilian Shan possibly existed before similar to 50 Ma; (2) the West Qinling was uplifted since similar to 50 Ma; (3) part of the Laji Shan was uplifted during similar to 39-30 Ma, and the entire Laji Shan was probably uplifted since similar to 30 Ma, separating the Xining from Xunhua-Linxia basins; and (4) the Qilian Shan was uplifted during the early Miocene, which together with climate change caused erosion and provenance changes. These results suggest that the NETP was uplifted since the early Cenozoic and sizeable parts of the NETP were probably uplifted by the early Miocene. |
