Abstract


Structure, sedimentary features, and biostratigraphy were taken into account to provide additional knowledge into the depositional conditions that influenced the sedimentary sequence along the southern coast of Zakynthos. This succession is exposed from Keri village to Ag. Sostis peninsula and appears to have been influenced by intense tectonic activity. The active tectonics resulted in the formation of at least four coarsening upward cycles. The co-occurrence of Bouma sequence subdivisions and slump horizons within the studied sediments suggest a deep-sea depositional environment. Grain size analysis indicates a regional swallowing upward trend. TOC and CaCΟ3 contents are presented with both positive and negative correlations while the TOC values indicate that the study area contain samples with source rock potential.
