项目摘要

We intend to study the biostratigraphy, palaeoecology and palaeoceanography of the Cenomanian - Turonian of five sections (Wunstorf, Konrad, Baddeckenstedt, Eastbourne, Goban Spur) with the focus on Wunstorf. These sections cover a transect from shallow water platform settings via hemi-pelagic black shales to pelagic chalk successions partly with black shales. High resolution stable isotope curves (δ18O, δ13C) provide a detailed stratigraphic framework for a high resolution correlation of each of these sites. This study aims at a better reconstruction of the paleoenvironment and palaeoceanography of different marine settings and the heterogenous sediment signals (black shale versus chalk) by analysing and interpreting the calcareous nannofossils. We want to understand the evolution and radiation patterns of calcareous nannofossils in different oceanographic environments during the peak of the Cretaceous greenhouse world. Our project has the following goals: a) to develop a high resolution biostratigraphie framework for the Wunstorf core, b) to understand the paleoecology and paleoceanography of different mid-latitudinal sites, c) to interpret both, black shale and chalk formation in the light of calc. nannofossil productivity, d) to decipher the evolution of calc. nannofossils during the peak of the global green house world.

我们打算研究Cenomanian的生物学，古生态学和古生物学 - 五个部分的Turonian（Wunstorf，Konrad，Baddeckenstedt，Eastbourne，Goban Spur），重点是Wunstorf。这些部分涵盖了从浅水平台设置通过Hemi-Pelagic黑色阴影到上层粉笔演讲的样品，部分是带有黑色阴影的。高分辨率稳定的同位素曲线（Δ18O，Δ13C）为每个位点的高分辨率相关性提供了详细的地层框架。这项研究旨在通过分析和解释钙质的纳米化石，以更好地重建不同海洋环境的古环境和古环境和古代造影。我们想了解白垩纪温室世界高峰期，在不同海洋学环境中钙质内化石的演化和辐射模式。我们的项目具有以下目标：a）为Wunstorf Core开发高分辨率的生物地层学框架，b）了解不同纬度位点的古生态学和古疗法，c）根据计算的光，以解释黑色页岩和粉笔形成。纳米化石生产率，d）破译计算的演变。全球温室世界高峰期的纳米化石。
