Paper Title:
Discussion of Paleocene-Eocene Boundary of SanShui Basin
  Abstract

Core SB-01 , located in SanShui Basin, contained two ostracode assemblages and two charophyte assemblages. Ostracode assemblages included Sinocypris nitela-Cyprois buxinensis-Limnocythere honggangensis assemblages (89.0-73.38m) and Sinocypris nitela-Cyprois buxinensis-Limnocythere honggangensis assemblages (73.38-0m); Charophyte assemblages consisted of Peckichara subspherica-Rhabdochara jiangduensis assemblages (89.0-73.38m) and Gyrogona qianjiangica-Obtusochara brevicylindrica(73.38-53.75m)assemblages. At 73.38 core depth, the abrupt change of microfossil assemblages took place, and δ13C and δ18O values of bulk carbonates also changed rapidly, the former decreased and the latter enhanced respectively. It consisted with the geological records of the Paleocene- Eocene Thermal Maximum ( PETM), hence Paleocene-Eocene boundary of SanShui Basin should be roughly placed at 73.38m core depth.
