Abstract: Abstract Venus has similar size, density and bulk composition as Earth, but has tectonically evolved clearly differently and this divergence remains enigmatic. Surface observations such as gravity, topography and surface age constrain Venus’ evolution, but… read more here.

Abstract: Inferences of mantle viscosity using glacial isostatic adjustment (GIA) data are hampered by data sensitivity to the space‐time geometry of ice cover. A subset of GIA data is relatively insensitive to this ice history: the… read more here.

DOI: 10.1093/gji/ggaa495
Abstract: Previous studies have shown that a low viscosity upper mantle can impact the wavelength of mantle flow and the balance of plate driving to resisting forces. Those studies assumed that mantle viscosity is independent of… read more here.
