A SCHEMATIC MECHANISM FOR STRIATED GROWTH OF SOLID BINARY-MIXTURES

It is shown, on the basis of a schematic model derived from that set up for the growth of plagioclase rocks by Haase et al. , that the interplay between diffusional transport and two slow molecular attachment kinetics in non-linear competition is sufficient to account for the possibility of striated growth (i. e. growth of a solid binary mixture with planar periodic composition oscillations in the growth direction.
