In southern Italy the Apenninic-Maghrebian Orogen developed during the Neogene Africa-
Europe collision as a regional-scale duplex structure. It shows an allochthonous
hangingwall, widely overlying a mostly carbonate footwall, consisting of the External Thrust
System. This formed since the Tortonian by the detachment of the sedimentary covers of the
continental margins of the Africa and Adria plates. In the Southern Apennines the duplex
geometry has favoured oil-trapping and fields have been detected in ramp-anticlines of the …

After studying the petroleum geology problems of the Central Mediterrranean Sea (Italy,
Tunisia) for 17 years I agree totally with the views expressed in the recent paper by F. Lentini
et al. I would like to add some remarks and conclude that there are other prospective zones
in the area. The Apenninic–Maghrebian–Orogen (AMO) has been pushed and thrust against
its foreland, which is formed by the Africa–Apulian microplate (Puglia peninsula in SE Italy),
the Hyblean plateau (southeast corner of Sicily) and the 'central platform'in Tunisia. On Fig. 1 …
