Field and theoretical investigations of strain localization: Effects of mineralogy, shear heating and grain size evolution on deformation in the Earth
… in the Earth: (1) viscous dissipation or shear heating (e.g., Braeck and Podladchikov, 2007; Braeck et al., 2009; Kameyama et al., 1999; Kelemen and Hirth, 2007; Ogawa, 1987), (2) grain size reduction (e.g., Braun et al., 1999; Montési and Hirth, 2003; Précigout and Gueydan, 2009), (3) …

The thermal and metamorphic evolution of the Northern Highlands Terrane, Scotland
… during deformation, otherwise known as shear heating. It is important to consider to how shear heating may contribute to metamorphism during orogenesis. This is challenging because there are few, if any, methods of relating observations from typical orogenic systems to magnitudes of …

Localization instability and the origin of regularly-spaced faults in planetary lithospheres
… but is instead localized on faults and ductile shear zones. In some regions such as the Central Indian Basin or martian ridged plains, localized shear zones display a characteristic spacing. This pattern can constrain the mechanical structure of the lithosphere if a model that includes the …

How deformation influences the flow and fracture of glacier ice
… ice viscosity. Firstly, I evaluate magnitude of heating by viscous dissipation and show that in many regions of ice streams, shear heating may create temperate zones from which meltwater drains to the bed. Secondly, I find that changes to the ice microstructure likely play a significant role in …

Different styles of deformation of the fore-arc wedge along the Chilean convergent margin : insights from 3D numerical experiments
… and vice versa. The model results show that shear heating at the plate interface is an important mechanism that should be taken into account. The models also show that the thermal condition at the downdip limit of the coupling zone leads to a sharp decrease of friction along the interface. …
