Phyllite of Bagrıkurt Formations contains dark color fragments, which have variable size (long axis: 1-18 cm) but usually elliptical shape. The fragments are quartzite, quartz-phyllite, chloritoid-quartz-phyllite, phyllite and metasandstone in composition. They are composed mainly of quartz (0.3-1 mm; 35-95%), colorless chlorite (0-50%), calcite (0-20%), chloritoid (0.1-0.4 mm;% 0-15), plagioclase(0.2-0.7 mm; 0-5%), colorless-light yellow and brown colored clinozoisite (0.4 mm;% 0-5), sericite (0-5% ), opaque minerals (0-40%), with accessory apatite (0.03 mm), tourmaline (0.25-0.6 mm), zircon and Fe3+ – riched sphene (0.1 mm). Lepidogranoblastic texture is dominant in the samples, but mortar texture also exists. Mineral assemblage of chloritoid, clinozoisite, sericite and chlorite suggest that the samples were possibly derived from a magmatic arc, and undergone a regional metamorphism together with its host formation in greenschist facies conditions.
