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… CONTINUE READING
