Insight into geologic evolution from changes to planetary landscapes by liquid flows
Session ID#: 248494
Session Description:
Landscape modification from flowing liquids archive crust-atmosphere exchange and interior evolution across solar system bodies. Some Martian paleo-channels may have been formed by low viscosity lava as an alternative to erosion by water (or ice-water, mud-water lahars). Venusian lavas are key to its landscape resurfacing as a function of interior evolution. Meanwhile, the roles of subglacial meltwater, precipitation runoff, and groundwater sapping in extensive valley networks remain enigmatic on Mars. Earth hosts not only subaerial fluvial systems as massive as the Mississippi, but also submarine canyons carved by water currents, and lava channels in mafic terranes like Iceland. Titan showcases how channels on bulk volatile planetary bodies resemble those on bulk silicate planets. Consequently, connecting diverse disciplines is crucial to discerning how liquid-solid interactions modify planetary landscapes. Accordingly, we welcome submissions on liquid-driven landscape evolution, including channel systems, to interrogate processes in planetary critical zones and changes in magmatic systems.
