Özet

The upper Cretaceous-Eocene Camardi Formation is exposed along the northern edge of the Ulukisla Basin (central Anatolia) and consists of turbiditic sediments. The sediment geochemistry has been studied in order to understand the provenance, source area weathering, and tectonic setting of the basin. Camardi Formation sediments are characterized by low to moderate SiO2 contents, variable abundances of major elements, and a relatively high proportion of ferromagnesian elements. Evidence from discrimination diagrams of sedimentary provenance, tectonic setting, major element geochemistry and Sc/Th, Cr/Th, Co/Th, Zr/Sc, La/Sc, La/Co, Cr/Sc, Y/Ni, and K/Rb values show that the Camardi Formation sediments were derived from mafic, felsic, and intermediate sources. The chemical index of alteration (CIA: 57.63-78.11) revealed moderately weathered source rocks. Then major and trace element concentrations indicated deposition in an active continental margin and continental island arc settings.
