The dynamics and evolution of Venus' mantle are of first-order relevance for the origin and
modification of the tectonic and volcanic structures we observe on Venus today. Solid-state …

The nearly global radar imaging and altimetry measurements of the surface of Venus
obtained by the Magellan spacecraft have revealed that deformational features of a wide …

Plates are an integral part of the convection system in the fluid mantle, but plate boundaries
are the product of brittle faulting and plate motions are strongly influenced by the existence …

The surface area of Venus (∼ 460× 106km2) is∼ 90% of that of the Earth. Using Magellan
radar image and altimetry data, supplemented by Venera-15/16 radar images, we compiled …

Venus is known to have been volcanically resurfaced in the last third of solar system history
and to have undergone a significant decrease in volcanic activity a few hundred million …

The effect of strongly temperature‐dependent viscosity on convection in the interior of Venus
is studied systematically with the help of finite element numerical models. For viscosity …

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 my it is …

▪ Abstract 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 …

Surface geologic features form a detailed record of Venus' evolution. Venus displays a
profusion of volcanic and tectonics features, including both familiar and exotic forms. One …
