Variation of diffusion coefficient (D) of divalent cations with ionic radius (IR) and its implications for the natural systems were discussed on the basis of the observed D's in the single crystal Mg- and Mn-olivines. The similar trend of variation observed for D-IR diagrams for the Mg- and Mn-olivines and periclase (MgO) suggests that the shape of the D-IR patterns is determined by the crystal structure and IR. Some of the distributions of the rare earth elements (La and Ce) observed in natural systems are consistent with the crystal-structure-controlled trend of D-IR variation.
