9405375 Stott The transition from Paleocene to Eocene time was one of the most important environmental and biological transitions in Earth history. PI, in collaboration with European colleagues, will continue to delineate the Paleocene/Eocene boundary, by its postulated carbon isotope excursion, in classic marine and non- marine sections. This boundary marks an important paleoclimatic, paleoceanographic and paleobiologic shift, currently the focus of interest for a large, international group of investigators. Detailed sampling of sections in Paris and London basins will be followed by isotopic analyses of soil carbonates, marine micro- and macrofossils. These data will be correlated with DSDP Site 550 (and 549), which provides a carbon isotope reference section, and other classic Paleocene/Eocene sites, e.g., in Wyoming.

9405375从古新世到始新世的过渡是地球历史上最重要的环境和生物过渡之一。PI将与欧洲同事合作，通过其假定的碳同位素漂移，在经典的海洋和非海洋部分继续划定古新世/始新世的界线。这一界线标志着一个重要的古气候、古海洋和古生物转变，目前是一个大型国际调查小组感兴趣的焦点。在对巴黎和伦敦盆地的部分进行详细采样之后，将对土壤碳酸盐、海洋微型化石和大型化石进行同位素分析。这些数据将与提供碳同位素参考剖面的DSDP站点550(和549)以及其他经典的古新世/始新世站点相关联，例如在怀俄明州。
