古新世-始新世极热事件(PETM)是新生代最重要的气候事件之一，目前对东特提斯区域该事件的研究程度较低。塔里木盆地西部和巴基斯坦Upper Indus Basin(上印度河盆地)分别代表东特提斯北缘和南缘，在古新世/始新世界线（P/E）时期具有不同的气候带、沉积环境和生物群落组成，对其研究有助于了解PETM事件在东特提斯的响应。本次研究拟重点对塔里木盆地西部巴什布拉克剖面和库孜贡苏剖面的齐姆根组开展高精度的多门类生物地层、古生态和碳同位素地层学研究，确定P/E界线的准确位置和PETM事件在干旱的近岸浅海环境下的不同生物记录和环境响应，同时对巴基斯坦Upper India Basin典型剖面的P/E界线地层开展生物地层、古生态和碳同位素分析，探讨温暖浅海环境下PETM事件的生物变化和环境响应。在上述基础上，综合分析PETM事件在东特提斯南、北缘的不同响应与关系。

The Paleocene-Eocene Thermal Maximum event (PETM) is one of the most important climatic events in Cenozoic, while the research on East of Tethys area is relatively less understood. The Western Tarim Basin in China and Upper Indus Basin in Pakistan represent the northern and southern ranges of the east Tethys respectively, which is helpful to recognize the PETM event in East Tethys. What’s more, there are the differences climatic zone, sedimentary environment and biota across the Paleocene/Eocene boundary (P/E). This research mainly focuses on the high-resolution biostratigraphy, palaeoecology and carbon isotopes of Qimugen Formation from Bashibulake section and Kuzigongsu section, Western Tarim Basin, and confirm P/E boundary and study the PETM event of biological records and environment in acid coastal area. Then, the P/E boundary, biostratigraphy, palaeoecology and carbon isotopes analysis of typical outcrop of the Upper Indus Basin will be taken. Finally, comprehensive analysis of the different responses and relationships of the PETM event between the southern and the northern ranges of east Tethys are carried out.
