The study area is located in in the northeast of Korkut district of Muş province and covers an area of approximately 200 km². Three stratigraphic sections were measured from the area as Kelereşdere, Taşlıca and Gültepe. A total of 506 m thick sedimentary sequence was measured along these sections and a total of 80 samples were collected as the material to be studied. All of the samples were analyzed by X-ray diffraction method, and the mineralogical compositions of the whole rock and clay fraction were determined. Quartz, feldspar, mica, calcite, amphibole and clay minerals were determined in whole rock compositions of the samples. In the clay fractions, smectite, illite, chlorite, chlorite-smectite, illitesmectite and serpentine minerals were detected as clay minerals. Scanning electron microscopy and energy dispersive spectroscopy studies were conducted on five selected samples. The presence of clay minerals such as serpentine, chlorite and smectite was observed in these samples. In this study, semi-quantitative percentage ratios of whole rock components by X-ray diffraction were also calculated. Pipette analysis was performed on selected samples and specific surface area was determined by BET method. Although the clay percentages obtained from the pipette analysis results and the specific surface area determination results were compatible, it was determined that they were not compatible with the semi-quantitative percentages.
