Effects of microstructural heterogeneity on the macroscopic spectrum of elastically accommodated grain-boundary sliding
Zhengxuan Li, John F. Rudge
Elastically accommodated grain-boundary sliding (EAGBS) is a plausible source of upper-mantle seismic attenuation and dispersion, yet classical theory predicts a localized Debye-li…
A Re-examination of Ellipticity Corrections for Seismic Phases
Stuart Russell, John F. Rudge, Jessica C. E. Irving +1
The Earth's ellipticity of figure has an effect on the travel times of seismic waves over teleseismic distances. Tables of ellipticity corrections and coefficients have been used b…
Gravity, topography, and melt generation rates from simple 3D models of mantle convection
Matthew E. Lees, John F. Rudge, Dan McKenzie
Convection in fluid layers at high Rayleigh number (Ra ) have a spoke pattern planform. Instabilities in the bottom thermal boundary layer develop into hot rising sheets…
Fast magma ascent, revised estimates from the deglaciation of Iceland
David W. Rees Jones, John F. Rudge
Partial melting of asthenospheric mantle generates magma that supplies volcanic systems. The timescale of melt extraction from the mantle has been hotly debated. Microstructural me…
Rate of Melt Ascent beneath Iceland from the Magmatic Response to Deglaciation
Isarapong Eksinchol, John F. Rudge, John Maclennan
Observations of the time lag between the last deglaciation and a surge in volcanic activity in Iceland constrain the average melt ascent velocity to be . Al…
The melting column as a filter of mantle trace-element heterogeneity
Tong Bo, Richard F. Katz, Oliver Shorttle +1
The observed variability of trace-element concentration in basaltic lavas and melt inclusions carries information about heterogeneity in the mantle. The difficulty is to disentangl…
Thermal impact of magmatism in subduction zones
David W. Rees Jones, Richard F. Katz, Meng Tian +1
Magmatism in subduction zones builds continental crust and causes most of Earth's subaerial volcanism. The production rate and composition of magmas are controlled by the thermal s…
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…
