Abstract

This study was performed to suggest convenient equations for quantifying Fe and K within the illite structure using relative intensities for the illite basal reflections. The 002/005 and 003/005 ratios were available for Fe and K quantifications, and equations could be derived as the following: CFe=(ln I002/005−1.807 ln I003/005+1.29)/(1.241 ln I003/005−3.843), CK=−(ln I002/005+0.121 ln I003/005−2.592)/(1.308 ln I003/005+1.984). The equations may obtain Fe and K contents within ca. ±0.05 atoms per half-unit cell, if incident radiation loss is minimized and basal reflection modification caused by expandable layers is eliminated. © 2004 International Centre for Diffraction Data.
