Measurement of Intergranular Diffusion in a Silicate System: Iron in Forsterite

Article metrics


MANY geochemists and petrologists1 concerned with the role of solid state diffusion in material transfer in silicate systems have noted the possibility that grain boundaries and dislocations might act as avenues for relatively rapid movement of the diffusing ions. Studies on metal systems are usually cited as evidence for this phenomenon. We wish to report some preliminary measurements on a silicate system where grain boundary diffusion seems to predominate in diffusive transfer.
