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: C Fe=(ln I002/005-1.807 1n I003/005+1.29)/(1.241 ln I003/005-3.843), CK=- (ln I002/005 + 0.121 ln I003/005-2.592)/(1.308 ln003/005+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.
