Abstract : The Sicilian-Tunisian Platform (STP) is a geological-geographical, mainly submarine area that is a continental crustal prong of North Africa. The northern margin of the platform is taken along the south side of the Sardinian Channel and the southern margin of the Tyrrhenian Sea. The eastern margin of the platform is taken along the steep slope of the eastern Sicily-Malta escarpment defining the western margin of the Ionian Sea. In the north this escarpment is well defined. The southern side of the eastern margin of the STP is taken along the less eastern side of the Medina Bank escarpment and south along the weak break at about 1,000 m water depth that separates the Platform from the Sirte deep. The southern and western margins of the platform are taken along major fault systems that separate normal African crust from extensional crust inlaid with younger sedimentary basins. The NE corner of the STP is taken through the Straits of Messina and the SW corner follows well defined flexures and regional faults marking the passage to the depressed crust of the Platform that contains many sedimentary basins. The NW and SE corners of the Platform are less well defined geologically.
