Aim of the open session is to create a multidisciplinary platform, where presentations which include studies on systematics in stable isotopes or studies which use stable isotopes as a tool, can be presented if no specialized session is organized elsewhere in the EGU General Assembly program.

The open session part includes a block of special interest on:

- Stable Isotope Analysis by Optical Spectrometry.

- Major Stratigraphic Boundaries and Isotopic Signatures.

Stable and radiogenic isotope trends play an important role in the interpretation of the causes and consequences of biotic turnovers at major
stratigraphic boundaries, such as the Precambrian-Cambrian (Pcb-Cb), Permian-Triassic (P/Tr), Triassic-Jurassic (Tr/J), Cretaceous-Paleogene (K/Pg) boundaries. Contributions are solicited of all isotopic studies

-radiogenic (Nd/Sm, Rb/Sr, 53Cr/52Cr etc.) as well as stable isotope studies (δ13C, δ8O, δ14N)- that are relevant for the understanding of those important events in earth history.

- Isotopic Studies in Cretaceous Research

Isotopic studies combined with further geochemical, lithological, mineralogical and paleontological records has been widely used in reconstructing Cretaceous marine and continental environments. The focus of this session is to present new advances, case studies and long term scientific debates concerned with boundary events, temperature calculations, atmospheric CO2 levels, switch on and off mechanisms as well as temporal extent of oxic and anoxic events. Further goals of the session will be the consistent correlation of isotope events between stratigraphic sections.
