Paterae On Io: Geologic Mapping Of Tupan Patera And Experimental Models, Megan Carolee Decker
Paterae On Io: Geologic Mapping Of Tupan Patera And Experimental Models, Megan Carolee Decker
Theses and Dissertations
Paterae cover approximately 2% of the surface of Io, Jupiter’s volcanically active moon. To understand the formation of these volcano-tectonic depressions we created a geologic map of a key region and compared this map with experimental models for Io paterae. Our mapping region is Tupan Patera, a patera that has experienced recent activity and is a detected hot spot. We identified four primary types of geologic materials: plains, patera floors, flows, and diffuse deposits. We constructed an experimental model to test previous suggestions that paterae may form as volatiles in the silicate crust are vaporized by rising magma, creating instability, …
