Session Introduction

2:20 PM

Nimmo F.* Mackwell S. J.

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.

2:30 PM

Byrne P. K.* Şengör A. M. C. Ghail R. C. Klimczak C. James P. B. et al.

Venus’ Highland Tesserae are Tectonic Counterparts to Earth’s Cratons [#2924]
The oldest places / On Venus might have secrets / Like Earth’s ancient rocks.

2:40 PM

Buck W. R.* Head J. W.

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.

2:50 PM

Maia J. S.* Wieczorek M. A. Plesa A.-C.

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.

3:00 PM

Panel Q&A

3:20 PM

Ernst R. E.* El Bilali H. Buchan K. L. Head J. W.

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.

3:30 PM

Weller M. B.* Harman C. E. Kiefer W. S. Way M. J.

Venus from the Interior to Surface: Atmospheric Evolution from Large-Scale Tectonic and Geodynamic Models Models [#1720]
Venus, Earth’s harsh twin / Why so inhospitable? / Deep secrets released.

3:40 PM

Semprich J.* Filiberto J.

Compositional Variation of Venusian Melts as a Function of Thermal Gradient and Protolith [#1468]
Below the surface / Rocks of Venus are melting / What are they made of?

3:50 PM

Zolotov M. Yu.* Mogul R. Limaye S. S. Way M. J. Garvin J. B.

Venus Cloud Composition Suggested from the Pioneer Venus Large Probe Neutral Mass Spectrometer Data [#2880]
Clouds and hazes could be saturated by Si-Fe-Mg-C rich alteration products of cometary dust and contain silica, sulfates, chlorides, and insoluble organics.

4:00 PM

Panel Q&A

4:20 PM

Gülcher A. J. P.* Yu T. Stadler D. Gerya T. V.

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.

4:30 PM

Schools J.* Smrekar S. E.

High Resolution Numerical Models of Corona Formation Integrating Magmatic Processes, Surface Fracturing, and Eclogitization [#1771]
What are corona? / Melt supports topography / Eclogite makes troughs.

4:40 PM

Davaille A.*

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.

4:50 PM

Surury S. Mason P. J.*

Mapping Recent Activity on Venus: Stress Field Analysis and Models of Evolution for Tectono-Magmatic Features in SW Parga Chasma [#2554]
Mapping ongoing activity on Venus through stress field analysis and models of evolution for tectono-magmatic features in SW Parga Chasma.
