Description :
Sedimentologic and stable isotopic studies in the Çal basin-fill provide new insights on the late Neogene–Quaternary climatic pattern in the eastern Mediterranean. An erosional unconformity separates the Pleistocene siliciclastic and calcrete deposits above as a single sedimentary unit resting on top of floodplain fines and restricted to the basin center. The stable isotopic analysis of the palustrine carbonates and pedogenic calcretes displays a wide range of values and the lack of significant δ18 O-δ13 C may indicate subhumid conditions or significant diagenetic alteration. The δ13 C values of these carbonates, organic δ13 C data from calcretes and floral remains indicate that the landscapes were dominated by C3 forest plants.
