英文摘要 | In 1999, Diexi paleo-dammed lake (2349 m a.s.l.) was discovered around Diexi town along the Minjiang River in Sichuan province. Diexi is located where the eastern edge of the Tibetan Plateau and the Sichuan Basin meet. The dammed lake was formed during the Last Glacial Maximum of the Late Pleistocene (~30,000 years ago) and began to empty about 15,000 years ago. The lacustrine sediments (up to 240 m thick) preserve abundant paleoenvironment information. In this paper, a mass of oxygen isotopes and C-14 dating from drilled cores are analyzed and discussed. The delta O-18 curve on the paleo climate from this section is comparable with the coeval paleo climatic curves of ice cores and karsts in China and others. Furthermore, the physical model testing has confirmed that the disturbed zones in the core are caused by strong earthquakes occurred at least 10 times, which implies strong crustal deformation, as an important driving force, affecting climate change. This study provides a new window to observe East Asian monsoon formation, paleoenvironmental evolution and the global climate change. |
