Shock metamorphism is a universal process governing material response

Dear Colleagues, We invite you to contribute to our session at the International Mineralogical Association (IMA) 2026 meeting in Nanjing, China, August 20–24, 2026: *Session 6.1: Multi-Scale Shock Metamorphism: Insights from Atoms, Minerals, Rocks, and Global Scales* Shock metamorphism is a universal process governing material response to extreme dynamic pressures in Earth and planetary systems. Hypervelocity impacts imprint matter with distinctive deformation and transformation features that span orders of magnitude in space and time. This session will explore shock-induced phenomena—from atomic-scale displacements to planetary-scale modification of crusts, environments, and habitability—integrating multiscale observations, experiments, and modeling to unravel the mechanisms and consequences of impacts and deformation. Understanding these effects is essential for reconstructing the history of cosmic collisions, interpreting impact craters, identifying shocked minerals in meteorites, and assessing the planetary consequences of impacts, including their role in mass extinctions and potential links to habitability. We welcome contributions on any rocky body or analogue—from Earth and the Moon to Mars, asteroids, and beyond—using natural samples (meteorites, impactites), laboratory experiments (shock recovery, gas-gun/laser-driven impacts, DAC studies), and theoretical or numerical modeling. Studies that integrate multiple scales, methods, and datasets (including remote sensing constrained by laboratory/in situ measurements) are especially encouraged. Confirmed invited speakers include: Dr. Xiande Xie (Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, China) Dr. Chi Ma (California Institute of Technology (Caltech), USA) Dr. Falko Langenhorst (Friedrich Schiller University of Jena, Germany) We invite you to please submit your abstract via the IMA 2026 website. The abstract deadline is *March 15, 2026*.
