英文摘要

The Paleocene epoch was characterized by short-lived warming events (hyperthermals), including the Latest Danian Event (LDE) and the Early Late Paleocene Event (ELPE), which provide critical analogues for understanding modern climate change. However, the global distribution and environmental impacts of these events remain poorly constrained, particularly in southern Xizang (Tibet), a key region within the eastern Neo-Tethys. This study presents larger benthic foraminifera (LBF) biostratigraphy and bulk carbonate carbon isotope data from the lower Zongpu Formation at the Chaqiela section in Gamba, southern Xizang. LBF assemblages constrain the studied interval to Shallow Benthic Zone 2 (SBZ 2) to SBZ 3. Carbon isotope records reveal two negative excursions within these zones, interpreted as the LDE (within SBZ 2) and the ELPE (within SBZ 3). These findings confirm the global nature of both events, highlighting their significance in the evolution of Paleocene hyperthermals and advancing our understanding of their spatial distribution.
