The Kizildere formation is a volcano-sedimentary formation implying a significant volcanic activity at the time of sedimentation. Sandstones in this formation are immature, quartz intermediate, feldsparlithic greywackes deposited close to a source area with little physical and chemical alteration. The compositional variation is scattered and considered as a mixture of clay, quartz feldspar and carbonate. K, Fe, Ti, Rb, Zr and probably Ba, Ni and Zn were added in sheet silicates (mica and clay). Al was added in clay as well as feldspar. Rb and Ba were substantially added in clay, mica and feldspar. Y was added in apatite, zircon and partly in clay and mica. The rocks reveal low to moderately weathered sources. Trace element patterns indicate a source composed largely of active continental margin environment. The rocks were derived from acid to intermediate source rocks with some input from basic rocks. The REE patterns indicate that the source rocks are young.
