Knowledge about the long-term history of the Asian monsoon climate is a prerequisite for better understanding regional- and global-scale climate change during the late Neogene and its link to the tectonic evolution and uplift of the Tibetan Plateau. Here we propose to continue our running multidisciplinary study on lacustrine deposits in Tibet; we focus on the Qaidam basin (NE plateau), which contains a unique record of aridification in central Asia. A 1400 m deep drill-core (SG-1: 940 m recovered in 2008, 1400 m to be reached in April 2010) and a surface profile provide a continuous sedimentary archive spanning the last ~8 Myr. For the future, we anticipate considerable synergy to result from a second drilling campaign (SG- 2) into an anticline structure nearby SG-1 that is planned by the same group within a launched BMBF program (1400 m: ~8-15 Ma). Integrating the results from the Qaidam basin with other data available from different areas of the Tibetan Plateau (Zada: ~9-1 Ma, Cuo’e: last ~2.8 Ma, Heqing and Zoîge: both last ~1 Ma) will allow us to conduct a comprehensive analysis of palaeoclimate proxies and related tectonic activities. The project is carried out in close cooperation by German and Chinese partners based on equal scientific work share, and bilateral financial support by the DFG, BMBF (German side), CAS, NSFC, and MST (Chinese side).

一个1400米深的钻孔岩心（SG-1: 2008年开采了940米，2010年4月将达到1400米）和一个地表剖面提供了一个跨越过去~ 8myr的连续沉积档案。对于未来，我们预计在SG-1附近的背斜构造中进行的第二次钻井活动（SG- 2）将产生可观的协同效应，该活动由同一小组在已启动的BMBF计划（1400米：~8-15 Ma）中规划。8 Ma、河清和zo<e:1>（均为最近~1 Ma）将使我们能够对古气候指标和相关构造活动进行全面分析。该项目由中德合作伙伴在平等分担科研工作的基础上密切合作，并由德国联邦政府、德国联邦科学基金（BMBF）、中国科学院、国家自然科学基金委员会和中国科技部（MST）提供双边资金支持。
