Geological processes such as volcanism, tectonics, and impacts are fundamental to the formation and evolution of the planets, moons, asteroids and comets of the solar system. These processes have largely contributed to shape planetary surfaces, each of them in different ways and at different rates. For example, asteroid impacts have played a critical role during planetary evolution, by delivering the primary constituents of asteroids and planets and by peppering their surfaces with impact craters. Volcanic and tectonic processes are efficient mechanisms to reshape planetary surfaces and provide valuable information about the planetary interior 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 and 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.
