SUMMARY The high resolution image of an apparently displacive defect in the long period ordered structure of Ag 3 Mg is analysed in terms of a simplified substitutional model. It is demonstrated by image simulation that the characteristics of the image could be described equally well on the basis of progressive relative substitution of Ag for Mg on two of the four sublattices in the structure.
