Dear colleagues, The abstract deadline is approaching this*Thursday (February 26, 2026, 23:59 ET / UTC−5)*, we would like to invite you to submit an abstract to *Goldschmidt 2026 for Session 02e: Understanding the Deep Earth through the Elastic and Transport Properties of Its Constituent Materials.* This session highlights recent experimental and theoretical advances in the elastic and transport properties of mantle and core minerals and melts, and how these results integrate with geophysical observations to improve models of Earth and planetary interior structure, dynamics, and evolution. We welcome contributions on elasticity and transport properties (e.g., electrical/thermal conductivity, diffusivity, viscosity) of deep Earth and planetary materials. Session details: https://conf.goldschmidt.info/goldschmidt/2026/meetingapp.cgi/Session/8729 *Keynote speaker: *Prof. Jin Zhang (Texas A&M University) *Invited speaker:* Prof. Wen-Pin Hsieh (Academia Sinica) We look forward to seeing you in *Montréal, Canada, July 12–17*. Best regards, Rong Huang, Yoshiyuki Okuda, Biao Wang, Takashi Yoshino
