Transient creep of olivine

Caption

Differential stress (color symbols), pressure and strain (gray circles), and temperature (orange line) plotted against time in a deformation run for an olivine sample. A sudden increase in temperature (from 570 to 870 K) was followed by a synchronized pressure jump (due to thermal expansion of olivine). The decrease in stress and the increase in strain (due to transient creep of olivine) was delayed by 25 seconds. Note that stress values are obtained from diffraction peaks of olivine (blue: 021; pink: 101; orange: 130).
