Abstract: A mineral of chlorite-type composition, classified as a daphnite, is shown to give a series of basal x-ray reflections which are incompatible with the normal chlorite structure. Fourier analysis indicates a modified distribution of Si and O atoms. A model is suggested in which some Si atoms are displaced and linked to the adjacent brucite-type layer, producing in effect kaolin-type structural units within the chlorite structure.
