Mixed-layer minerals were analyzed by far infrared (FIR) spectrometry. The FIR spectra show two bands, which occur at 84-87 and 108-114 cm -1  for mixed-layer illite-smectite (I-S) and at 71-79 and 103 cm -1  for mixed-layer phlogopite/vermiculite (P-V). The 103 cm -1  band seen in the P-V series from Palabora is independent of K +  content and is attributed to lattice vibrations. The lower wavenumber band observed at 85 cm -1  for I-S mixed-layers and 71-73 cm -1  for P-V mixed-layers corresponds to K +  fixed in the two-layer stacking sequences. This low wavenumber band shifts to higher wavenumbers as the thickness of coherent scattering domains increases: shifting toward 97 cm -1  for the illite end-member of the I-S series and to 79 cm -1  for Palabora phlogopite, the endmember of the P-V series.
