The 10th International Clumped Isotope Workshop (ICIW10) is a community conference focused on the measurement and natural chemistry of multiply substituted isotopologues—so-called clumped isotopes—and closely related subfields of stable isotope geochemistry, including triple-oxygen isotope systems.

ICIW10 is organized by the Department of Earth Sciences at Utrecht University in the Netherlands and will be held on university campus from June 23-26, 2026.

About Utrecht
