Volcanic and tectonic processes have profoundly shaped the surface of terrestrial planets and satellites. This session aims to compile all facets of volcanism, tectonism, and associated interactions observed in our solar system. By providing a forum for a broad range of discussions, these observations and interpretations will be investigated and reviewed in the light of our current understanding of related processes on Earth. Comparative studies and work on active volcanic/tectonic systems on Earth using multi‐instrumental, remotely sensed, experimental, computaional, and field data are welcome.
The session will address, but is not limited to, the following topics:
- geomorphological characteristics of volcanic edifices, vents, and fissures
- volcano‐tectonic deformation, growth and collapse on global and local scales
- tectonic structures, faulting, and fracturing processes
- magma related morphologies
- intrusion processes, geometry, and associated faulting
- crustal stress and strain analysis
- volcaniclastic deposits and their implications for eruptive styles, rates, and frequency
- composition (spectral, meteoritic, etc.) and rheology of lava flows
- volatile release through eruptions and its impact on atmospheres
- melt generation, lava extrusion, and crustal deformation caused by large impactors
- cryovolcanism, mudvolcanism, and other comparative processes
