In the Çayırhan-Beypazarı (Ankara) coal field, there are two coal seams, the lower and upper seams, in the Çoraklar Formation of Late Miocene age, and only the upper seam is mining by underground methods. The upper seam is divided into two levels, the first (Tv) and second (Tb) seams by the tuffaceous dirt band with approximately 1 m thickness. In the coal field the profile coal samples and rock samples were collected from the Tv and Tb seams at the 3 locations of the A, B and C underground coal mines, and 44 coal samples and 15 rock samples have been evaluated. In this thesis, variations of especially mineralogical and trace element concentrations within the Tv and Tb seam have been studied in detail.
