With regard to the temperature dependence, we must recognize the existence of some temperature above which the binding energy of the solute atoms to the fault is smaller than the energy of thermal motion; thu

Now wvaph = -Pwv2h so that (aAG/ap)T = AV and any pressure-variation of AF (through elastic moduli) is irrelevant. A lattice diffusivity increasing with increasing pressure implies a negative activation volume AV. However, it is not certain that the simple effect on lattice diffusion was measured
