1.0 1.5 Fe 2 0 3 [%] Fig. 4. Diagram of average deformation versus Fe 2 0 3 % — for a considerable number of samples the differences between the measured values are low, close to the errors of the methods; — considering the degree of order, the differences in kaolinite content had been taken into account when correcting the peak height, but the differences in particle size were excluded because the amount of the samples was not sufficient for the preparation of particle separates. The relationships between the parameters of lattice order are better expressed by the linear correlation of deformation in the 001 direction with the degree of order, according to which the degree of order decreases with increasing deformation. The lowest DO-value (32—for a kaolinite from Cserszegtomaj) corresponds to a deformation as high as 13.1. Most of the samples belong to the range of medium degrees of order, but the differences among them are large enough to express the trends between the two parameters, as shown by the value of the correlation coefficient (Fig. 2). Among the investigated kaolinites only a few specimens are of hydrothermal origin, therefore the observation that these kaolinites have the highest DO and deformation parameters, cannot be generalized.
