SUMMARY:Goldschmidt 2026\, Session 02h - Under pressure: from chemical bonding to planetary structures and evolution
DESCRIPTION:Dear colleagues\,\nWe hope you will join a scientific session focusing on bonding at extreme conditions at the 2026 Goldschmidt Conference in Montreal\, Canada\, July 12-17\, 2026.\nOver the past few decades\, observations of exotic bonding behaviors\, complex stoichiometries\, and low-symmetry arrangements in simple and binary systems—including noble-gas compounds—have progressively reshaped our picture of Earth’s structure and evolution\, as well as processes such as volcanism and tectonics. Rather than a relatively simple\, uniform deep Earth that can be described as consisting of a few high-symmetry phases\, we now envision a more mineralogically differentiated and chemically intricate planet\, where minor constituents can play major roles. This view aligns with the heterogeneities revealed by seismology. The exotic nature of bonding and crystal chemistry that governs Earth’s inner structure and dynamics is gradually being uncovered\, yet remains far from fully understood and generalized.\nThis session brings together experimental and theoretical studies that advance our understanding of the chemistry\, bonding\, and resulting physical properties of matter in planetary deep interiors\, as well as the extreme-condition static and dynamic processes that shape planetary compositions and structures. These include the identification of new compounds and phases\, determinations of material properties at high pressure\, and investigations of bonding mechanisms under extreme conditions. We also seek contributions that articulate open problems and challenges warranting further\ninvestigation. \nKeynote speaker: Thomas S. Duffy\, Princeton University \nPlease consider submitting an abstract by February 26\, 2026\nWe look forward to meet you in Montreal\, Canada\nBarbara Lavina (U. of Chicago & Argonne Natl. Lab.)\, Stefano Racioppi (University of Cambridge)\, Martin Rahm (Chalmers University of Technology)
