Viscous Relaxation as a Probe of Heat Flux and Crustal Plateau Composition on Venus
[#1280]
Relaxation of crustal plateaus precludes a quartz-rich composition. Anorthite plateaus would imply Venus heat fluxes lower than radiogenic heat production.

Compression and Tension in Model Venus Highlands Partly Decoupled from Mantle Flow
[#2375]
Simple models show that the flow of hot lower crust on Venus driven by mantle motions can produce both compressive and rifted highlands.

The Mantle Viscosity Structure of Venus
[#1737]
A Bayesian investigation of the dynamic signature of Venus’ gravity and topography indicates the presence of a low-viscosity zone in the upper mantle.

Mafic Dyke Swarms: Key to Understanding Magmatism and Tectonics on Venus
[#2603]
Mafic dyke swarms are key to understanding venusian magmatism, tectonics, and perhaps also its atmospheric evolution.

Corona Structures at Topographic Margins on Venus Reveal Interior Dynamic Processes
[#1419]
With a joint study of mission data analysis and 3D modeling of asymmetrical coronae on Venus, we make predictions on the processes that shape(d) Venus’ geology.

What VERITAS Will See in Venus Artemis Coronae: An Earth Early Archean Plate Tectonics System?
[#2550]
Laboratory models suggest that present-day Venus could give insights on Archean Earth, but we need VERITAS high-resolution data to get these informations.
