In the western Mediterranean, the relative motions of the Eurasian and African plates produce a combination of lateral and compressive forces, concentrated in a zone known as the Azores–Gibraltar Fault Zone. Along its northeast margin, the African plate is bounded by the Red Sea Rift where the Arabian plate is moving away from the African plate.
The geology of Europe is varied and complex, and gives rise to the wide variety of landscapes found across the continent, from the Scottish Highlands to the rolling plains of Hungary. Europe's most significant feature is the dichotomy between highland and mountainous Southern Europe and a vast, partially underwater, northern plain ranging from ...
The geology of Sicily (a large island located at Italy's southwestern end) records the collision of the Eurasian and the African plates during westward-dipping subduction of the African slab since late Oligocene. [1] [2] Major tectonic units are the Hyblean foreland, the Gela foredeep, the Apenninic-Maghrebian orogen, and the Calabrian Arc.
These plates comprise the bulk of the continents and the Pacific Ocean. For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi) African plate – Tectonic plate underlying Africa – 61,300,000 km 2 (23,700,000 sq mi)
Forming the Atlantic segment of the boundary between the African and Eurasian plates, the AGFZ is largely dominated by compressional forces between these converging (3.8 to 5.6 mm/a (0.15 to 0.22 in/year)) plates, but it is subject to a dynamic tectonic regime that also involves extension and transform faulting.
The subduction of the African plate slab has led to the development of a volcanic arc, known as the South Aegean Volcanic Arc (SAVA). Magmatism began in the early Pliocene , with typical arc-related andesite – dacite volcanism, stretching from the Saronic Gulf in the west to Santorini in the east.
However, the Somali plate covers much of eastern Africa, creating the East African Rift. In the eastern Mediterranean, the Aegean Sea plate, Anatolian plate and Arabian plate also form a boundary with the African plate, which incorporates the Sinai Peninsula, Gulf of Aqaba and the coastal Levant via the Dead Sea transform.
Alpine cycle sedimentary rocks are situated between the European hinterland in the Rhodope Massif and Serbo-Macedonian Massif and northern fore-region of the African plate. External zones include the Paxi Zone, encompassing the islands in the Ionian Sea with dolomitized limestone from the Jurassic and Cretaceous-Miocene marl and gypsum.
