Nanocrystalline principal slip zones and their role in controlling crustal fault rheology
Principal slip zones (PSZs) are narrow (< 10 cm) bands of localized shear deformation that
occur in the cores of upper-crustal fault zones where they accommodate the bulk of fault …

Effects of temperature on the frictional behavior of material from the Alpine Fault Zone, New Zealand
RD Valdez II, H Kitajima, DM Saffer - Tectonophysics, 2019 - Elsevier
Temperature is widely believed to act as a primary control on fault rheology, and therefore
on the distribution of seismicity along plate boundary faults. However, there are few detailed …
