 The Apulia Platform, which is part of the stable and relatively undeformed foreland of the Apennine thrust belt, is bounded on both sides by basinal deposits; westward the margin is buried under the Apennine thrust sheets, to the east the adjacent paleogeographic domains are the vast Ionian Basin to the south and the Umbria-Marche Basin to the north.To the west, the Apulia Platform plunges downfaulted underneath the terrigenous sediments of the Apennine foredeep; to the southeast, the Jurassic–Early Cretaceous margin lies 20–30 km offshore from the present Apulia coastline.The Gargano Promontory is an area of the Apulia Platform.
