The latest Cretaceous was characterised by perturbations in the global carbon cycle which are assumed to have been associated with ephemeral glaciations. In order to understand the forcing mechanisms, their global significance, and the regional response to these events it is necessary to improve our presently available stratigraphic framework. The pelagic limestone successions at Gubbio, Umbria Marche Basin, Italy have a detailed magnetostratigraphy and serve as tropical reference for the biozonation with calcareous nannofossils and planktonic foraminifera. We propose to develop a high-resolution carbon isotope stratigraphy at the sections Contessa Highway and Bottaccione using bulk-carbonates to resolve short-lived isotopic events between 80-65 Ma calibrated to paleomagnetic reversals and bioevents. The development of such an integrated stratigraphic framework is important for the global correlation between low and high latitudes and shelf and deep-sea sections. It provides the unique opportunity to recognize leads and lags between the carbon cycle, sea-level changes and ocean circulation of the different oceanic ecosystems.

最近的白垩纪的特点是全球碳循环的扰动，这被认为是与短暂的冰川作用有关。为了了解这些事件的强迫机制，它们的全球意义和区域响应，有必要改进我们现有的地层框架。意大利翁布里亚马尔凯盆地古比奥的远洋石灰岩序列具有详细的磁性地层学，可作为钙质超微化石和浮游有孔虫生物分带的热带参考。我们建议开发一个高分辨率的碳同位素地层学的部分Contessa公路和Bottaccione使用散装碳酸盐解决短命的同位素事件之间的80-65 Ma校准到古地磁反转和生物事件。建立这样一个综合地层框架对于全球低纬度和高纬度以及大陆架和深海剖面之间的相互关系十分重要。它提供了一个独特的机会，可以认识到不同海洋生态系统的碳循环、海平面变化和海洋环流之间的超前和滞后。
