FOURIER TRANSFORM INFRARED SPECTROSCOPIC CHARACTERIZATION OF KAOLIN GROUP MINERALS FROM THE MAIN SLOVAK DEPOSITS

Rok, strany: 1997, 3 - 10

FTIR spectroscopy was used to study Slovak kaolinites and halloysites of various geological origin. Twenty seven samples ranging from well-ordered to very poorly-ordered kaolinites were examined to explore correlation between the degree of structural disorder (or crystallinity) and their geological origin. The highest degree of ordering was found for hydrothermal and sedimentary kaolinites. Poorly ordered kaolinites and halloysites belong to the group of weathered kaolins or to the kaolin clays. The degree of crystallinity, determined by IR spectroscopy (OH stretching and bending regions) was compared with that measured by XRD. Good relationship between IR and XRD measures of disorder was found for the kaolinites of hydrothermal and sedimentary origin, while only partial correlation was found for weathering kaolinites and kaolin clays.
