In recent years, a large debate has taken place on the deep structure of the southern Apennines and on the roles and spatial-temporal variations of thin-skinned vs. thick-skinned styles of thrusting. Surface geology coupled with abundant subsurface data from the oil industry point out that the Apennine accretionary wedge presently forms an allochthon overlying foreland carbonate platform strata (Apulian Platform) continuous with those exposed in the Apulian promontory to the NE. The tectonically buried portion of the Apulian Platform was involved in the final shortening phases, giving rise to reverse-fault-related, open, long-wavelength folds that form the hydrocarbon traps for the significant oil discoveries in southern Italy. Thin-skinned thrusting and associated large amounts of horizontal shortening and extremely high shortening rates have been proposed for the subsurface Apulian Platform carbonates based on the interpretation of deep seismic reflection data.
