“…The upper Campanian-Maastrichtian Bozova Formation in the Mazıdağı area is characterized by clayey limestone and marl (KÖYLÜOĞLU, 1988;ÇORUH et al, 1997). The overlying Lower Germav Formation consists of calcareous mudstone-marl, and was deposited in relatively deeper, basinal conditions (CATER & GILLCRIST, 1994) as evidenced by the presence of planktonic foraminifera, plant fragments, inoceramids, and ammonites in Campanian-Maastrichtian marls, shales and limestones (YILMAZ et al, 2018). The Bozova Formation on the Arabian Platform is the objective of this study.…”

“…The Cretaceous sequences in the NW Mardin area are divided into seven formations (Fig. 2) composed mainly of limestones and dolomites with minor amounts of siliciclastic sequences (MULAYIM et al, 2016;YILMAZ et al, 2018;HOŞGÖR & YILMAZ, 2019). In the study area, basement rocks crop out close to Mazıdağı village and are characterized by Ordovician sandstone and shale (KELLOG, 1960;KURU, 1987).…”

“…The late Campanian sea-level record according to HAQ ( 2014) is characterized by a sequence boundary and 100 m sea-level fall in the R. calcarata biozone, and CC23a/UC 16 nannofossil biozones. This sequence boundary is over- (SUNGURLU, 1974;YILMAZ et al, 2018). lain by another higher sequence boundary at the G. aegyptiaca biozone.…”

The sedimentology, geochemistry and paleontology of the pelagic upper Campanian Maastrichtian Bozova Formation in the "Mazidag" (Mazıdağı) - Mardin area, SE Turkey, reveal paleoceanographic and paleoecological changes for the first time. A 119.25 m-thick composite stratigraphic section is characterized by alternating marls, clayey limestones, shales, and black shales; no coarse siliciclastic admixture or turbidite intercalations were recorded in the section. Biostratigraphic data indicate the presence of the Radotruncana calcarata Zone, and the UC15de/UC16 nannofossil zones. Stable isotope and elemental geochemical analyses have been carried out in the studied section. The isotope curves display similar patterns compared to reference curves from European and Chinese basins in the same interval. The prominent negative carbon isotope excursion determined in the upper interval can be correlated with the Late Campanian Event. Proxy elements display generally two relative rising trends in productivity from the lower part and the middle part of the succession. The lower part of the section records relatively more dysoxic/anoxic conditions and coincides with common black shale beds. The presence of both diverse planktonic foraminifera and calcareous nannofossils in the studied interval indicates a fully marine, warm-water, low-latitude Tethysian oceanic environment. In addition, the plant fossils derived from the nearby land mass indicate that a tropical humid climate was similar to that in northeast Australia. Therefore, warm water, tropical humid atmospheric conditions developed in the studied area causing the rise in productivity, precipitation and transportation of plant debris into offshore environments.

The International Geoscience Programme Project IGCP 609 addressed correlation, causes and consequences of short-term sea-level fluctuations during the Cretaceous. Processes causing several ka to several Ma (third- to fourth-order) sea-level oscillations during the Cretaceous are so far poorly understood. IGCP 609 proved the existence of sea-level cycles during potential ice sheet-free greenhouse to hothouse climate phases. These sea-level fluctuations were most probably controlled by aquifer-eustasy that is altering land-water storage owing to groundwater aquifer charge and discharge. The project investigated Cretaceous sea-level cycles in detail in order to differentiate and quantify both short- and long-term records based on orbital cyclicity. High-resolution sea-level records were correlated to the geological timescale resulting in a hierarchy of sea-level cycles in the longer Milankovitch band, especially in the 100 ka, 405 ka, 1.2 Ma and 2.4 Ma range. The relation of sea-level highs and lows to palaeoclimate events, palaeoenvironments and biota was also investigated using multiproxy studies. For a hothouse Earth such as the mid-Cretaceous, humid–arid climate cycles controlling groundwater-related sea-level change were evidenced by stable isotope data, correlation to continental lake-level records and humid–arid weathering cycles.
