Fluor-phlogopite

Figure 4.20 Calibration curve of 4th order. Dashed line Calculated only with Ag reflections. It results an erroneous extrapolation to smaller angles. Full line Same procedure but with the inclusion of additional fluor phlogopite reflections. (Wong Ng Hubbard (1987) ).

In this way, Sunagawa et al (1968) identified polytypes IM, 2Mi, 2M2, 20 and 37 in synthetic fluor-phlogopite, and confirmed the presence of polytypes with longer period, whose stacking sequence was however too complex to be identified only on the basis of the surface morphology.
