 On the basis of physical stratigraphic relationships and of the presence of evident bounding surfaces, the Jurassic-Eocene succession can be subdivided into six major packages of sediments, which can be classified as second-order depositional sequences.The lower three sequences (Callovian to Albian) are represented by the entire spectrum of sediments from platform to slope and basin, and the younger ones (Cenomanian to Lutetian) largely by slope and basin deposits.Probably the most typical and significant feature of the Gargano slope and basin setting is the presence of huge megabreccia bodies which, in terms of sequence stratigraphic terminology, can be interpreted as typical lowstand wedges.
