With less than a week to go to the abstract deadline, we draw your attention to the Goldschmidt session 03i (https://conf.goldschmidt.info/goldschmidt/2026/meetingapp.cgi/Session/8991): Linking Deep Crustal Processes and the Timescales of Archean-Proterozoic Lithosphere Evolution (session in honor of Priyadarshi Chowdhury) at Goldschmidt, 12-17 July in Montreal, Canada. Abstract submission deadline is February 26, 2026 (23:59 ET/UTC-5). Details can be found here: https://conf.goldschmidt.info/goldschmidt/2026/cfp.cgi Keynote speaker: Taras Gerya Invited Speakers: Chris Yakymchuk, Ming Tang, Mahyra Tedeschi We invite you to contribute to this exciting session in honor of Priyadarshi Chowdhury, who received The Mineralogical Society of America Award for 2025. Priyadarshi’s research has made high-impact contributions to first-order problems in lithosphere dynamics, and this honorary session will address key topics including: the chemical composition of continental crust across time, the rates, timing, and processes of early continental crust formation; the temporal character of tectonothermal events under hotter geotherms; the insights that metamorphic-magmatic timescales provide into evolving tectonic styles and thermal regimes and ultimately, the stabilization of felsic crust and cratons. We welcome contributions from researchers at all career stages and across diverse fields, including metamorphic and igneous petrology, isotope and trace element geochemistry, diffusion kinetics, geochronology, and geodynamic modelling. The session aims to foster interdisciplinary dialogue on the processes and tempos that shaped Earth’s early evolution. Session conveners: Sumit Chakraborty, Jamie A. Cutts, Daniele Regis, Roberta L.
