Geological processes such as volcanism, tectonics, and impacts are fundamental to the formation and evolution of the planets, moons, asteroids and comets of our Solar System. These processes are the primary agents responsible for the shaping of planetary surfaces, each of them in different ways and at different rates. For example, asteroids and comets have played a critical role during planetary evolution, by delivering the primary constituents of planetary bodies and by promoting resurfacing via impacts. Volcanic and tectonic processes are efficient mechanisms to reshape planetary surfaces and provide valuable information about planetary interiors and evolution. The study of geological processes in the Solar System is at the crossroad of many scientific disciplines using either in-situ sampling and analysis, remotely sensed data, or experimental and numerical modelling.

This session aims to compile all facets of volcanism, tectonism, impact cratering, and their associated interactions with other geological processes observed in our Solar System. By providing a forum for a broad range of discussions, these observations and interpretations will be investigated and (re)viewed in the light of our current understanding of related processes on Earth. Comparative studies on volcanic/tectonic systems, impact structures, and other processes on Earth using multi-instrumental, remotely sensed, experimental, computational, or field data are particularly welcome.
