Quantitative determination of the mineral composition of core samples originating from deepbores of the South Great Plain was performed by means of X-ray diffractometry. The difficulties occurring at the determination of muscovite, illite, illite/montmorillonite and chlorite were investigated. The change in mineral composition in the fraction less than 10 microns as compared to the average sample was investigated separately. It was stated that there is a correlation between the quantities of FeO and chlorite of the investigated samples. A definite relationship can be determined between the amount of chlorite and that of B, V, Ni and Cr. Positive correlation can be determined between the ppm values of Sr and the carbonate minerals. In the samples of 10 microns the quantity of calcite increased at the expense of dolomite, while dolomite is mostly absent in the fraction of 10 microns. In the core samples of the "Makó depression trench" albite and acidic plagioclase were found only in the Lower Pannonian strata, in the Upper Miocene formations only albite occurs in determinable quantity. On the basis of the diffractograms the potash-feldspars are absent, under microscope their quantity is subordinate.
