Özet
In the lake which was formed as a result of the blocking of Çaki{dotless}t River by landslide in the investigation area (Belemedik -Pozanti{dotless}/Adana), 20 m thick delta-lake facies complex deposits were formed. 4 main facies association were identified in Belemedik Delta. First of them is composed of conglomerates having varied grain size and sandstones. This facies association shows plannar cross bedding and graded bedding and represents proximal part of the braided river system. The second-facies association consists of conglomerates, sandstones, siltstones and claystone. Channel geometry is typical in this association. Alternating sand-silt laminations and small scaled cross beddings and ripple marks are abundant near upper levels. Third facies association represented by siltstone, claystone and sandstone alternations. Ripple laminations and cross beddings are abundant. That facies association shows delta bottom set deposits. Fourth-facies association is characterized by large lateral extension of plannar or ripple laminated sediments. Sandstones in this association have fine to very fine grain size. This facies association shows that it occurred to by the deposition of materials like silt and fine sand by turbidity currents in the front part of the delta environment (lake environments).
