Figure A3.6. Deconvoluted XRD spectrum for sample BT; see Electronic Supplement 2 for details on the methodology. This sample contains significant kaolinite, which causes interference on the 2.58Å band. Polytype quantification is therefore somewhat uncertain and the results should be regarded with caution. While all illite peaks could be identified, the 32.1 °2θ peaks in the medium and fine fractions are unusually high. The reason for this is uncertain, but we have excluded these peaks from the calculation of the mean. Black curve original data, blue curves deconvoluted single peaks, red curves – – – illite polytype-sepcific peaks, dashed line background, green curve modelled curve (sum of all blue curves), grey vertical – – lines positions of polytype-specific illite peaks. –
