Abstract :This study focuses on the investigation of the relationships between mineralogical (content, average and largest grain diameter) and engineering parameters of rocks. Polished section analyses of rocks were performed via clemex image analysis system and motorized table which are integrated into the trinocular research microscope that is a modern technique. Strong correlations (r=0.76–0.81) were found between largest grain diameters of pyrite and engineering parameters. The correlation degree between pyrite content and the engineering parameters was generally obtained as moderate (r=0.52–0.71). The similar correlation (r=0.47– 0.70) between average grain diameters of pyrite and engineering parameters was determined. Meaningful relationships between the internal friction angle ( f ) with the average and largest grain diameter was found as 0.47 and 0.86, respectively. These results demonstrated that the presence of pyrite in the rocks can affect the engineering parameters of the rocks.
