High‐temperature creep experiments were made on olivine single crystals under compressional stress to large strains. At strains larger than about 40 to 60%, dynamic recrystllization occurs and cellular wall dislocation structure is formed. Recrystallized grain size dg(µm) and cell wall spacing ds(µm) are dependent upon applied stress σ(MPa) as: and
