Mesozoic and Cenozoic Sequence Stratigraphy of European Basins

Sequence and biostratigraphic analysis of the margin of the Apulian carbonate platform in the Montagna della Maiella (central Italy) reveal a platform margin evolution that is controlled by long-term sea-level changes, tectonism and changing platform morphology. The Upper Cretaceous to Miocene strata can be subdivided into six supersequences that are separated by deeply incised truncation surfaces. Biostratigraphy documents a major hiatus for all but one of these boundaries. The supersequences reflect distinct stages of platform development, thus the \ndepositional systems remained the same within each supersequence but changed across the supersequence boundaries. \nThe Apulian platform grew on a passive margin of the Jurassic-Cretaceous (Neo-) Tethys. During the early platform history, subsidence rates decreased exponentially with time and controlled the long-term aggradation potential of the platform. The generally decreasing total subsidence rates permitted the basin in front of the platform to be filled up by the Late Campanian strata (Supersequence [SS] 1), resulting in a change from aggradation to progradation. This enabled slope carbonates of Late Campanian to Late Eocene age (SS 2 to 4 and lower part of SS 5) and finally shallow-water platform carbonates of Late Eocene to Late Miocene age (upper part of SS 5 to SS 6) to prograde basinwards.
