Sicily lies on the complex convergent plate boundary between the African Plate and the Eurasian Plate. The geology of the western part of the island is dominated by the Gela Nappe, a thin-skinned fold and thrust belt. The Gela Nappe consists of Pliocene-Quaternary age sedimentary rocks deposited in the earlier foredeep, thrust up onto the thick carbonate sequence of the Pelagian-Hyblean Platform of the African Plate.
