Grain-size dynamics beneath mid-ocean ridges: Implications for permeability and melt extraction
Andrew J. Turner, Richard F. Katz, Mark D. Behn
Grain size is an important control on mantle viscosity and permeability, but is difficult or impossible to measure in situ. We construct a two-dimensional, single phase model for t…
An experimental test of the viscous anisotropy hypothesis for partially molten rocks
Chao Qi, David L. Kohlstedt, Richard F. Katz +1
Chemical differentiation of rocky planets occurs by melt segregation away from the region of melting. The mechanics of this process, however, are complex and incompletely understoo…
Three-field block-preconditioners for models of coupled magma/mantle dynamics
Sander Rhebergen, Garth N. Wells, Andrew J. Wathen +1
For a prescribed porosity, the coupled magma/mantle flow equations can be formulated as a two-field system of equations with velocity and pressure as unknowns. Previous work has sh…
Glacial cycles drive variations in the production of oceanic crust
John W. Crowley, Richard F. Katz, Peter J. Huybers +2
Glacial cycles redistribute water between oceans and continents causing pressure changes in the upper mantle, with consequences for melting of Earth's interior. Using Plio-Pleistoc…
Pipe Poiseuille flow of viscously anisotropic, partially molten rock
Jane Allwright, Richard F Katz
Laboratory experiments in which synthetic, partially molten rock is subjected to forced deformation provide a context for testing hypotheses about the dynamics and rheology of the…
