We review recent developments in the study of volcanism and tectonics on Venus. Venus’s crust is basaltic, dry, and probably about 30 km thick. The mantle convects, giving rise to plumes, and has a similar composition and mean temperature (»1300 ‐ C), but a higher viscosity (»10 20 Pa s), than that of the Earth. Inferred melt generation rates constrain the lithospheric thickness to between 80 and 200 km. The elastic thickness of the lithosphere is about 30 km on average. The present-day lack of…

Rheological decoupling at the Moho and implication to Venusian tectonics

Deformation experiments show that crustal plagioclase is much weaker than mantle olivine at conditions corresponding to the Moho in Venus, and this strength contrast may produce a mechanical decoupling between the Venusian crust and interior mantle convection.

Estimating Venusian thermal conditions using multiring basin morphology

Despite their critical roles in Venus’s geological evolution, neither heat flow through the Venusian lithosphere nor the corresponding tectonic regime in its geological past is well constrained.

Dynamics of fault motion and the origin of contrasting tectonic style between Earth and Venus

It is proposed that strong dynamic weakening in friction is a key factor leading to substantial dynamic weakening on Earth but not on Venus, leading to the contrasting tectonic styles between Earth and Venus.

Volcanism as an active planetary process on Venus

Volcanism has been a crucial planetary process in the evolution of Venus, shaping the surface and contributing to the formation of the atmosphere and clouds. Some of the key outstanding questions are

Mechanisms for cessation of magmatic resurfacing on Venus

[1] Proposed mechanisms of resurfacing on Venus about 0.3–1 Gyr ago usually involve either some form of tectonic resurfacing in which Venusian lithosphere is recycled mechanically or magmatic



An episodic hypothesis for Venusian tectonics

It is suggested that episodic plate tectonics occurs on Venus; episodes of rapid plate tectonics are separated by periods of surface quiescence. For the last 500 ± 200 m.y. it is postulated that the

Constraints on the thermal evolution of Venus inferred from Magellan data

One interpretation of the Magellan data suggests that the cratering record on Venus was erased by a global resurfacing event, or events, the latest ending about 500 m.y. ago. In this

Mean age of rifting and volcanism on Venus deduced from impact crater densities

UNLIKE the extensively cratered highlands of the Moon and Mars, the surface of Venus does not preserve a record of heavy bombard-ment from the early history of the Solar System1-3. Those craters that


Recent deformation rates on Venus

Constraints on the recent geological evolution of Venus may be provided by quantitative estimates of the rates of the principal resurfacing processes, volcanism and tectonism. This paper focuses on

Convection‐driven subsolidus crustal thickening on Venus

We analyze the phenomenon of subsolidus crustal flow in response to mantle convection and test the hypothesis that Venusian crustal plateaus such as Ovda Regio formed over mantle downwellings. We

The gabbro-eclogite phase transition and the elevation of mountain belts on Venus

Maxwell Montes, standing up to 7 km above the adjacent highland plateaus, constitute the highest mountain belt on Venus. Because the thickness of the crust is likely to be limited by the

Anatomy of a Venusian hot spot - Geology, gravity, and mantle dynamics of Eistla Regio

Eistla Regio is a series of broad swells, each up to a few thousand kilometers in diameter, in the equatorial highlands of Venus. It is characterized by strong positive free-air gravity anomalies,

A tectonic resurfacing model for Venus

Two remarkable aspects of the population of impact craters on Venus are as follows: that craters at all sizes are indistinguishable from a random population; and that the vast majority of craters
