  • Environmental changes related to sea-level fluctuations driven by the EarthÂ’s orbital perturbation in the Milankovitch frequency band are evidenced by three to four orders of cycles recorded by Cretaceous shallow water carbonate rocks. The hierarchical stacking pattern of cycles and their interpretation in terms of sequence stratigraphy have been used to identify gaps in sedimentary sequences as well as in assembling a chronostratigraphic diagram. It allowed an assessment of both the duration and the position of the omissions in the stratigraphic record. Moreover, the sequence stratigraphic approach to well stratified shallow marine carbonate platform section provided a dynamic picture of their depositional history and allowed a clearer understanding of the relationship among climatic changes, sea-level oscillations and sedimentation. This paper demonstrates that a) it is possible to construct a consistent stratigraphic framework based on sedimentary cycles b)carbonate platform strata are a very useful tool to derive an orbital chronostratigraphy for global correlations.

Abstract
  • Detailed sedimentological analysis of Aptian/Albian shallow water carbonate platform strata from Monte Faito, southern Italy, reveals composite sea-level change. The organization of the lithofacies and their related diagenetic overprint have allowed the identification of 50 elementary cycles. They often show exposure-related diagenetic features superimposed on subtidal deposits, suggesting drops of relative sea-level. Elementary cycles are grouped into 16 bundles forming 6 superbundles. The hierarchical organization of the cycles are interpreted as related to composite eustatic sea-level fluctuations driven by the EarthÂ’s orbital perturbation in the Milankovitch frequency band. Moreover, the systematic variation of superbundle thickness and the general evolution of the lithofacies reflects variations of accommodation potential defining longer-term environmental changes. Different lithofacies forming elementary cycles are frequently separated by bedding planes that, when viewed in a sequence stratigraphic context, are interpreted as transgressive surfaces, maximum flooding surfaces or sequence boundaries. This allows the recognition of lowstand, transgressive and highstand deposits in the cyclic units. Considering both the bundle/superbundle ratio and the sequence stratigraphic interpretation of the superbundles, a chronostratigraphic diagram illustrating both gaps at bundle level and their expected location along the section was created. It establishes that the section developed over about 2.4 My. (literal)
