Subglacial hydrology as a control on emergence, scale, and spacing of ice streams
T. M. Kyrke-Smith, R. F. Katz, A. C. Fowler
Observations have long associated ice streams with the presence of meltwater at the bed. More recently, theoretical models have been able to reproduce ice-stream behaviour as a con…
The role of volatiles in reactive melt transport in the asthenosphere
Tobias Keller, Richard F. Katz
Experimental studies of mantle petrology find that small concentrations of water and carbon dioxide have a large effect on the solidus temperature and distribution of melting in th…
Melt transport rates in heterogeneous mantle beneath mid-ocean ridges
Samuel M. Weatherley, Richard F. Katz
Recent insights to melt migration beneath ridges suggest that channelized flow is a consequence of melting of a heterogeneous mantle, and that spreading rate modulates the dynamics…
Torsion of a cylinder of partially molten rock with a spherical inclusion: theory and simulation
Laura Alisic, Sander Rhebergen, John F. Rudge +2
The processes that are involved in migration and extraction of melt from the mantle are not yet fully understood. Gaining a better understanding of material properties of partially…
Consequences of viscous anisotropy in a deforming, two-phase aggregate. Why is porosity-band angle lowered by viscous anisotropy?
Yasuko Takei, Richard F. Katz
In laboratory experiments that impose shear deformation on partially molten aggregates of initially uniform porosity, melt segregates into high-porosity sheets (bands in cross-sect…
Melt-preferred orientation, anisotropic permeability, and melt-band formation in a deforming, partially molten aggregate
Jesse Taylor-West, Richard F. Katz
Shear deformation of partially molten rock in laboratory experiments causes the emergence of melt-enriched sheets (bands in cross-section) that are aligned at about 15-20 degrees t…
