RELATION BETWEEN STRUCTURAL DISORDER AND OTHER CHARACTERISTICS OF KAOLINITES AND DICKITES

A suite of Georgia kaolinites, ranging from well-ordered to very poorly ordered samples, were studied to explore correlations between degree of structural disorder, geological environment, Fe**3** plus content, Fe**3** plus electron paramagnetic resonance (EPR) spectrum, and infrared (IR) hydroxyl-stretching band frequencies and bandwidths. Samples from different localities showed a wide range of disorder which appears to be related to differences in their geological environments. High iron content correlated strongly with low degree of order. The areas of both the I and E components of the EPR spectrum and the fractional I area correlated inversely with degree of order. Results of Fourier-transform IR studies of kaolinites and dickites are discussed.
