“…We suggest a shelf break situated only a few kilometres north of the studied area, possibly linked with normal faults further north. This fits with deeper marine marls characterizing the offshore area only 20 km north of the studied sections at Rizan Aneiza (Martinotti 1993) and the occurrence of phylloceratid ammonites in the Lower Aptian sediments probably suggesting that deeper marine conditions were present in an area close to the studied ramp sediments (Lehmann et al 2007). However, an odd taphonomic history has been suggested for this group of ammonites, with surfacing and floating of shells first that is followed by resinking by cameral puncture, and therefore a substantiation of an autochthonous origin can be complex (Maeda & Seilacher 1996).…”

The Upper Barremian-Albian Levant Platform was studied in North Sinai and Israel (Galilee and Golan Heights) by bio-and lithostratigraphy, facies analyses, and sequence stratigraphy. Integrating shallow-marine benthic foraminifera (mainly orbitolines), ammonite, and stable isotope data resulted in a detailed stratigraphic chart. Transects across the shallow shelf in both regions are based on facies analysis and form the basis for depositional models. In both transects five platform stages (PS I-V) were identified, which differ significantly in their stratigraphic architecture, mainly controlled by local tectonics, climate and second-order sea-level changes. In North Sinai, a transition from a shallow-shelf that is structured by sub-basins through a homoclinal ramp into a flat toped platform is recognized, while the sections in North Israel show a transition from a homoclinal ramp into a fringing platform. Local normal faults influenced the depositional architecture of the Upper Barremian-Lower Aptian strata in North Sinai and were attributed to syn-rift extensional tectonics. Four second-order sequence boundaries were identified, bounding Mid-Cretaceous Levant depositional sequences. These well-dated second-order sequence boundaries are MCL-1 (Late Barremian), MCL-2 (earliest Late Aptian), MCL-3 (Lower Albian), and MCL-4 (Late Albian). The sea-level history of the Levant Platform reflects the Late Aptian-Albian global long-term transgression, while the second-order sea-level changes show good correlation with those described from the Arabian plate.

“…The local biostratigraphy of the Cenomanian outcrops has been based mainly on ammonites (Lewy and Raab, 1978). Planktic foraminifers have been found sporadically in these outcrops, and the derived planktic foraminiferal biostratigraphy of the Cenomanian has been established on the coastal plain and offshore, where foraminifera occur more frequently (Lipson-Benitah, 1980, 1994Martinotti, 1993;Lipson-Benitah et al, 1995, 1997).…”

We present data on the calcareous nannofossil distribution in the Albian-Cenomanian borehole CT8 obtained from the Carmel area, NW Israel. The nannofloral assemblage consists of 113 species, with Watznaueria spp. dominating the entire succession. The detailed calcareous nannofossil biostratigraphy of this section is established, and seven nannofossil (sub)zones are recognised. For the first time the age of the Tavasim Tuff (V 2) is biostratigraphically identified as Late Albian. The quantitative analysis of the calcareous nannofossils suggests warm, open marine or coastal, mainly oligotrophic conditions throughout the entire succession of borehole CT8, with evident fluctuations of temperatures and fertility and a general trend towards cooling in the uppermost part of the sequence (Middle-Late Cenomanian). Temperature and nutrient variations correspond to those in the western Tethys, thus suggesting at least a supra-regional extent of processes detected in the Carmel Region. The biostratigraphy shows no evidence of hiatuses in the studied section, but the absence of positive carbon isotope anomalies associated with the Oceanic Anoxic Event (OAE) 1d and Mid-Cenomanian Event elsewhere suggests that the OAE 1d is possibly missing in the studied section due to a hiatus around the Isfiye Fm. / Arqan Fm. boundary.
