摘要: The Apenninic foreland shows two distinct structural signatures comparing the central Adriatic Sea and Puglia region. During Pliocene-Pleistocene underwent high subsidence rates due to eastward rollback of hinge west dipping subduction. region Bradanic foredeep are located southward along strike in same foreland, but, contrast with Adriatic, after Pliocene-early Pleistocene they uplift since middle Pleistocene. geometry kinematics frontal accretionary wedge related changed from that moment on between areas. At front northern Apennines, off scraping continued, whereas southern Apennines were buckled. Those differences interpreted as being larger subduction rate lithosphere (70 km thick) respect thicker (110 km). different thicknesses continental crust inherited Mesozoic rifting disrupted plate. appear have controlled variable degree flexure its asthenospheric penetration rate. Tremiti E–W alignment is right-lateral lithospheric transfer zone those tectonic regimes. consequent dip sections (steeper Puglia) could also explain lower elevation compared their central-northern sector.
