Rheology
Rheology is the study of the ductile flow of minerals in response to stress. The Mantle Processes group uses rheological analysis of peridotites to examine a range of mantle processes, including the formation of localized zones of deformation; the relationship between olivine lattice preferred orientation and seismic anisotropy; and the effect of orthopyroxene on olivine deformation.
