Geophysical analysis methods were applied on 2D seismic reflection profiles offshore Cyprus improving the tectono-stratigraphy and sedimentary architecture knowledge on some of the Easten mediterranean hydrocarbon key provinces (Eratosthenes Seamount, Nile Delta, Levantine, Herodotus and Antalya basins). 3 Detailed seismic interpretation allowed the mapping of petroleum traps, and deformation areas correlated to their key geomorphology features, with some being detailed for the first time through this study. New potential hydrocarbon plays are illustrated through this work along with a proposed conceptual model of the Eratosthenes Seamount that offers a more in depth understanding of their creation and structure. New findings from 12 boreholes and spring waters on hydrogen generation on the Troodos Massif ophiolite, illustrate higher pH values than previously identified of up to 11.5 value. This strengthens further previous assumptions on low temperature serpentinization processes occurring on the island of Cyprus. The presence of Hydrogen (0.2 %) gas, frames and enhances our theory of a prospective hydrogen generation system, correlated to the ultramafic rocks (source), Messinian succession sediments (seal), limestone reefs (reservoir) and faults (migration) present in the subsurface. At ~5.97 Mya the Messinian Salinity Crisis changed the landscape of the whole Mediterranean region through the new evaporite and clastics deposits, contributing to the hydrocarbon and possible hydrogen systems their key sealing element (Messinian deposits). The study of the stratigraphy, sedimentology and geology of the relatively recent (Messinian – recent) deposits give insights to some of the continental margins, deep basins and salt structures development in the region (Western Alboran basin, Gulf of Lion, Sicily channel, South Adriatic, Levantine basin). Extensional and compressional salt tectonics dominate the region with the creation of salt diapirs, anticlines and salt rollers being the most prominent features related to the halite presence.
