Detailed sedimentological analysis in Makrylia cross-section deposits showed atleast five coarsening-upward cycles that were developed in a shelf environment. Themain lithology is sandy silt and the sediments were transported as homogenous suspensionin a low energy environment that deposited in a shallow water basin. Thecontent of calcium carbonate (CaCO3) is low and tends to increase to the coarsegrainedclasts. Organic carbon (TOC) measurements showed the presence of manysamples with high content in TOC suggesting potential hydrocarbon source rocks.There is mostly a negative correlation between CaCO3 and TOC introducing generallyanoxic conditions. Biostratigraphic analysis showed that the studied depositsare of Pliocene age that were precipitated in alternating conditions of oxic- anoxicevents. According to the above results and taking into account previous results fromthe surrounding sediments it seems that the studied deposits accumulated in a shallow,low energy, intra-mountain basin at the margins of the main Ierapetra basin.
