1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: <mvarasreus@xxxxxxxxx> Dear Colleagues, If you are working in non-traditional stable isotopes and high-temperature geochemical processes, consider submitting your abstract to the 2022 Goldschmidt session 3g â??Non-traditional stable isotopes as new windows into the evolution of the silicate Earthâ??. This yearâ??s meeting will be held in Honolulu, Hawaii, in a hybrid format (on-site and virtual), from 10-15 July 2022. The deadline for receipt of abstracts is 1 March 2022. A description of the session is provided below and we are happy to have Dr. Anat Shahar as our keynote speaker. We look forward to meeting at Goldschmidt, either in person or virtually, Best wishes, Maria I. Varas-Reus, Francois Tissot, Mauricio Ibañez-Mejia, Heye Freymuth and Haolan Tang For further information about the session, please visit the page https://urldefense.com/v3/__https://2022.goldschmidt.info/goldschmidt/2022/meetingapp.cgi/Session/3401__;!!IKRxdwAv5BmarQ!PXa-_7eSyNkZBYRWN85bdObdF9_5Xkn-JEL11MAb3YKR0jg8VyRJJ_Jxp0MGWbI$ <https://urldefense.com/v3/__https://2022.goldschmidt.info/goldschmidt/2022/meetingapp.cgi/Session/3401__;!!IKRxdwAv5BmarQ!K0HEH18WUEHziDsMiv7q08uLDQAUR6HP-3lmJkR637aqZikouXyY1QE7Aa1Wo0Q$> Session Name: *3g Non-traditional stable isotopes as new windows into the evolution of the silicate Earth* Session Description: In recent years, and thanks to improved analytical capabilities, heavy stable isotopes (e.g., Mg, Fe, Se, Ti, Zr, Mo) have emerged as powerful new windows into high-temperature geochemical processes. Isotope ratios that were once considered invariant now reveal permil to sub-permil variations that allow us to study diverse problems ranging from core formation to mantle and crust evolution as well as subduction recycling. Some heavy stable isotopes are also sensitive to changing redox conditions at the surface through geological time and may offer unique insights into Earthâ??s coupled endogenic and exogenic evolution into a habitable system. In this session, we invite submissions focusing on emerging and more mature â??non-traditionalâ?? isotope systems that: (1) contribute to our basic understanding of these systems (e.g., constraining modern global cycles, understanding isotopic fractionations, theoretical systematics), (2) make use of these proxies to address first-order scientific questions regarding the evolution of Earthâ??s lithosphere. We welcome studies exploring the full range of temporal and/or length-scales - from Hadean to modern; from micron size systems (single-crystals and below) to global reservoirs - where the stable isotope chemistry of heavy elements are now being used.
