“…Onshore studies have identified several candidate source rock deposits in the sedimentary succession of the eastern Mediterranean Sea (Karakitsios andRigakis 1996, 2007;Karakitsios et al 2001;Zelilidis et al 2003Zelilidis et al , 2016Karakitsios 2013;Moforis et al 2013;Maravelis et al 2014Maravelis et al , 2015aMaravelis et al , 2016Maravelis et al , 2017Tserolas et al 2018Tserolas et al , 2019Bourli et al 2019a, b;Grohmann et al 2019;Leila et al 2020) in terms of Mesozoic oil-prone and Cenozoic gas-prone source rocks. Oil production in the study area is generally present in the sub-salt pre-Messinian sequences, while post-Messinian deposits have shown prospects for biogenic gas and are relatively immature in respect to hydrocarbon generation.…”

This study details new geochemical analysis from an outcrop in Crete to improve understanding of the hydrocarbon potential of the southern margin of the Hellenic Arc along the continental convergent zone of the central Mediterranean Ridge. Seventeen samples were collected from the Late Miocene sub-salt sedimentary succession of Plouti section in central Crete and were studied in terms of their organic geochemical features using Rock-Eval VI pyrolysis. Results of this investigation revealed intervals with sufficient organic material of good enough quality and quantity to be considered as potential source rocks. The obtained data generally present poor to fair and/or good in some cases hydrocarbon generation potential. The TOC values range from 0.03 to 1.99%, with an average fair (2.1 mg HC/g rock) hydrocarbon potential. A Type III kerogen was identified, indicating a terrestrial origin organic matter. T max and Production Index values suggest that the most promising parts of the section (organic-rich sediments) are immature with respect to oil generation and have not experienced high temperature during burial. Overall, the present study offers the opportunity to advance our understanding on the hydrocarbon potential onshore Crete and further investigate hydrocarbon prospectivity in the adjoining area, and particularly, the Greek part of the Mediterranean Ridge, a region with crucial economic and strategic importance.
