Meter-scale cycles as a proxy for the evolution of the Apulian Carbonate Platform during the late Cretaceous (Llogara Pass, Albania)

On the architecture of intra-formational Mass-Transport Deposits: Insights from the carbonate slopes of Great Bahama Bank and the Apulian Carbonate Platform

“…The block-in-matrix model cannot be used to explain observations from the MTDs along the APCP margin, such as the dominance of slumps in the Cretaceous-Paleocene series in the study area (Albania; Le Goff et al, 2015a and in the Gargano Promontory (Italy; Morsilli and Moretti, 2011;Korneva et al, 2016;Jablonská et al, 2016Jablonská et al, , 2018. Contorted layers are the predominant pattern in carbonate MTDs, with little evidence for lithified blocks scattered in a fine-grained matrix.…”

“…(ii) Variations in sediment production and accommodation space resulting from the interplay between eustatic sea-level fluctuations and subsidence rates (Schlager, 1993). Excess carbonate production in both systems is attested by biogenic skeletal export onto their adjacent prograding slopes (Eberli and Ginsburg, 1987;Le Goff et al, 2015a). Flat-topped carbonate platforms are surrounded by deeper basins and straits into which excess carbonate debris is resedimented.…”

“…A number of studies focused on the identification, mapping and dating of the Upper Cretaceous to Paleocene MTDs in the APCP carbonate series in Albania (Rubert et al, 2012;Le Goff et al, 2015a. The Mali Gjere mountain ridge covers ca.…”

The dismantling of the Apulian carbonate platform during the late Campanian – early Maastrichtian in Albania

“…This major unconformity is coeval with megabreccia accumulation overlain by a pelagic interval in the Ionian Basin succession (Luperto-Sinni and Borgomano, 1989;Bosellini et al, 1999;Graziano, 2013). This unconformity, however, is not identified in Albania (Le Goff et al, 2015b); ii) In the Gargano (Fig. 1B), shallowwater carbonates are replaced by base of slope and pelagic carbonates from the Santonian e early Campanian.…”

“…The Upper Cretaceous carbonate platform successions preserved in the peri-Adriatic region are mainly made up of wellbedded peritidal to shallow-subtidal limestones, commonly organized in meter-scale cycles (Borgomano, 1987(Borgomano, , 2000Vlahovi c et al, 2005;Spalluto, 2012;Le Goff et al, 2015b). This monotonous sedimentation pattern is interrupted several times during the Late Cretaceous, namely: i) in Croatia, the Adriatic carbonate platform drowned; an event occurring near to the Cenomanian e Turonian boundary.…”
