Dear all, We cordially invite you to contribute to our session EMRP1.4: Theoretical and experimental advances and applications in exploring deep planetary interiors https://meetingorganizer.copernicus.org/EGU23/session/45917 ABSTRACTS SUBMISSION DEADLINE: January 10th 2023 EMRP1.4 session description: Theoretical and experimental approaches play an essential role in modern geophysics and geochemistry to improve our understanding of the structure and evolution of deep planetary interiors by determining phase diagrams and constraining the chemical and physical properties of planet-forming materials at relevant pressure and temperature conditions. Recent advances in theoretical computations and the constant increase of computational power have made it possible to overcome many of the limits of time and length scales faced by atomistic simulations and have allowed us to explore the behavior of more realistic geo-materials. State-of-the-art static and dynamic experimental methods have also extended the quantity and quality of possible measurements, pushing research into previously unreachable conditions and providing new insights into relevant physical properties that are crucial for modelling geological processes at various time scales. The coupling of laboratory and theoretical data with geophysical observations and field investigations is fundamental, with implications ranging from the improved understanding of Earth to the accurate modelling of planets within the solar system or exoplanets. In this session, we welcome presentations of new experimental data, computational results, and technical developments addressing the properties of behavior of realistic rock-forming materials and iron alloys. We encourage interdisciplinary studies combining experiments, modelling, and analytical results with geophysical and geochemical observations. The EGU General assembly 2023 (23-28 April) is announced as a hybrid event. We look forward to your contributions and hope to see many of you either in Vienna or online.
