Clay minerals belong among the most widespread minerals in the earth's crust rock system. Despite the rapid development of new analytical techniques, accurate identification of these minerals in the rocks is rather difficult and often inaccurate. One of the promising combination of analytical methods suitable for the characterization of clay mineral mixtures are combination of thermal analysis and FTIR spectroscopy. In this work, the assay mixtures were prepared from the common clay minerals with fraction of particle size less than 5 μm varying by a proportional representation of the base constituents of the mixture ranging from 10% to 90%. The mixtures thus prepared should at least partly simulate natural mixed clay structures. The aim was to find characteristic peaks on DTA curves as well as absorption bands in IR spectra suitable for the identification of clay minerals in mixtures and at the same time to determine the minimum content of detectable minerals.
