Stable isotopes in geosciences - open session, including blocks of special attention
Convener: Pier De Groot  | Co-Conveners: Ana-Voica Bojar , Erik Kerstel , Roland Bol , Wolfram Meier-Augenstein 
 / Mon, 08 Apr, 08:30–12:00  / Room Y10
 / Attendance Mon, 08 Apr, 17:30–19:00  / Yellow Posters

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

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

- Stable Isotope Analysis by Optical Spectrometry.
In recent years optical stable isotope ratio analyzers have seen a tremendous increase in end-user acceptance and ever-wider application in both laboratory and field studies. Here we provide a podium for new developments in this field, whether it concern the optical technology or its interfacing to peripheral equipment, as well as specific demonstration or intercomparison studies.

- Isotopes and Isoscapes as Tool for Forensic Provenancing
The session aims to provide a forum for isotope based climate and geochemistry related mapping and modelling work and how this is or can be combined with applied provenancing casework be it in the context of archaeology, crime investigation, food authenticity, ecology, environmental forensics or wildlife forensics. The conveners therefore invite contributions on light and heavy isotope and instrumental and analytical approaches, theoretical consideration and discussion of actual research and casework.

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