The high-temperature creep behavior of the Mg, (Mg, Fe), Fe, and Co silicate olivines is reviewed and compared. The results are examined specifically in terms of the point defect chemistry of these materials with particular emphasis on modifications proposed to constitutive laws for high-temperature steady-state creep to account for the nucleation and migration of jogs and kinks as one possible resolution of the discrepancy between activation energies for self-diffusion and those for creep.
