Dear colleagues:

We would like to draw your attention to our session 03h in Goldschmidt 2025 (6-11 july) in Prague:

Theme 03h: Decoding Earth's Lithosphere: Stable Isotope Approaches from Microscale to Macroscale

This session aims to explore the latest advances in understanding the behavior and applications of stable isotopes, highlighting their potential to decode processes shaping Earth’s lithosphere across scales. We aim to bring together researchers with diverse perspectives to discuss stable isotope interpretations, fractionation mechanisms, new methodologies, and interactions between geological reservoirs. We encourage analytical, experimental, and theoretical contributions addressing these exciting topics and look forward to the insights that will emerge from this collaborative effort.

The deadline for abstract submission will be in 4 weeks (26th, February, 2025).

Our keynote speaker, Dr. Ralf Halama, will present: “Tracing subduction zone processes using light stable isotopes (Li, B, N)”.

So, please don’t hesitate to submit your abstract and make your research shine. You can submit your abstract at https://conf.goldschmidt.info/goldschmidt/2025/cfp.cgi https://conf.goldschmidt.info/goldschmidt/2025/cfp.cgi.

We are looking forward to meeting you in Prague.

Best regards,

Jie Xu, Hamed Gamaleldien, Johannes Pohlner, Sheng-Ao Liu, Qasid Ahmad and Stephan König

Session Description https://conf.goldschmidt.info/goldschmidt/2025/meetingapp.cgi/Session/7685:

Stable isotopes provide new opportunities to improve our understanding of the diversification of Earth’s reservoirs and elemental cycling between them. Equilibrium and kinetic stable isotope fractionation between minerals and fluids/melts and mixing between different sources cause variations in stable isotope compositions. Knowledge of these mechanisms can illuminate various processes shaping the Earth’s lithosphere, including interactions with the mantle and surface reservoirs. We aim to bring together researchers from diverse backgrounds who seek a better understanding of stable isotope fractionation, both traditional and non-traditional, and leverage it to develop new tools for deciphering processes across all scales within the geologic record. This includes several key aspects to be addressed, such as (1) mineral-scale quantification of equilibrium stable isotope fractionation factors and diffusion-driven isotope fractionation; (2) development of methods based on stable isotope fractionation, including geothermometers and other proxies, and source fingerprinting schemes; (3) investigation of the interaction between Earth’s crust and surface processes, including weathering, sedimentation, and biological activity; and (4) quantifying and interpreting stable isotope compositions to constrain macro-scale processes related to lithosphere evolution, such as subduction recycling, interactions with the mantle, igneous differentiation, and potentially associated ore deposit formation. We thus welcome analytical, experimental, and theoretical contributions addressing these topics. By exploring these themes, the session will provide an integrated perspective on the behavior and applications of stable isotopes for decoding the complex processes on all scales shaping Earth’s lithosphere and related reservoirs.
