This session aims to bring together scientists who investigate variations of ´non-traditional´ stable metal and metalloid isotopes (e.g. B, Ca, Cd, Cr, Cu, Fe, Li, Mg, Pb, Si, Zn) in the terrestrial and aquatic environment and focus on new applications and analytical advances. As the sensitivity of analytical instruments has improved greatly in the recent past, even small natural variations can be identified and used to shed light on processes occurring within organic and inorganic systems in the terrestrial and aquatic ecosystems. Moreover, enriched isotopic spikes provide a valuable tool to study dynamic processes in biological or ecological systems. Element cycling during chemical weathering processes and soil-plant interactions, as well as the anthropogenic impact of industrial and agricultural activities are thus traceable with stable metal and metalloid isotopes. Since this research area is still quite new and the community depends on technological improvements, contributions concerning methodological and technical advances in this field are greatly encouraged.


Stable Isotope records (C, O, H, N, S, Sr, etc.) have been largely used for investigating continental (palaeo)-environments. The session will address changes at different time and spatial scale and invites:
- Contributions that brings together various continental isotope records in order to explore the evolution of Earth and life over time;
- Contributions that use stable isotopes as well as palaeontological, mineralogical, major and minor elements, etc in order to elucidate the interreaction betwen different reservoirs and the (palaeo)-climatic response.
- Contributions that use stable isotope as well as other records in order to correlate stratigraphic sequences.
