The Mediterranean region is composed of several frontier basins which has attracted the interest of international oil companies due to recent discoveries of natural gas offshore Israel and Cyprus in the Levant Basin (Dalit [0.5Tcf], Mari-B [1 Tcf], Tamar [8.4 Tcf], Leviathan [16 Tcf]; Aphrodite-A [3.5 Tcf]; Zohr [16 Tcf]. The Levant Basin formed in the Early Mesozoic in the context of the fragmentation of the Pangea supercontinent and the separation of Laurasia from Gondwana. This basin was initially a rift type basin initiated during Late Triassic, and evolved later on through compression tectonics. The post-rift phase prevailed since the Late Jurassic and is expressed by the gradual initiation of a passive margin on which extended carbonate platform developed. Each of these platforms have shown a similar geological history recording the geodynamic evolution of the Neothetys. Based on Geophysical (magnetics) and reflection data (2D – TWT and PSDM), it has been proven that the Jurassic and the Cretaceous carbonate platforms are built on top of a continental fragment inherited from the rifting. Similarly, throughout Northern Ionian, the Apulian platform has a distinct geometry with consistent seismic responses of the carbonates. Also, south of Crete the seismic interpretation shows some isolated carbonate buildups beneath the Messinian salt. Starting from the platforms that are identified in the Levant Basin this contribution aims to describe and discuss the tectonostratigraphic, the sedimentary architecture and morphologies of successive shelf edges (from the Jurassic to the Pliocene) of the Mesozoic carbonate. This work will be achieved by showing a detail interpretation of the lateral facies changes (based on other ancient analogues) on Eratosthenes and Apulian Carbonate platforms. Finally, the different controlling factors related to the drowning of carbonate platforms and thus the demise of carbonate factories will be discussed.
