“…This period (and especially the late Cretaceous epoch) differed from the other time intervals of the Mesozoic by two distinctive features. First, despite the warm planetary climate (Kauffman and Johnson, 2009;Hay and Floegel, 2012;Zalasiewicz and Williams, 2012), glacial advances are known (or, at least, hypothesized) in the Cretaceous (Frakes and Francis, 1988;Frakes and Krassay, 1992;Alley and Frakes, 2003;Miller et al, 2005;Bornemann et al, 2008;Galeotti et al, 2009;Moriya, 2011;Maurer et al, 2013;Peropadre et al, 2013). Second, the breakup of Gondwana reached its end, and there were active tectonic reorganizations in the Pacific (Cogné et al, 2006;Ruban et al, 2010;Seton et al, 2012;Chatterjee et al, 2013).…”

a b s t r a c tGlobal sea-level has changed in a cyclic manner through geologic history, but the regularities of these changes are yet to be fully understood. Despite certain (and sometimes significant) differences, the available Mesozoic eustatic curves permit the outlining of long-term eustatic cycles, which are provisionally defined as cycles recognizable at the stage level and higher. Interpretation of the Triassic eustatic curves indicates two orders of long-term cycles and a 1st-order sea-level rise throughout the entire period. The Jurassic eustatic curves imply cyclicity of one or two orders, and a 1st-order eustatic rise during the entire period is also evident. Most challenges are interpretations for the Cretaceous; two to four orders of long-term eustatic cycles can be established for this period. Generally, the hierarchy of the long-term eustatic cycles might have changed through the Mesozoic. If so, and if one considers differences of cycles of the same order between the periods of this era, it is difficult to apply "standard" hierarchical classifications to the documented cycles. The hypothetical uncertainty of the hierarchy of the Mesozoic long-term eustatic cycles is an important challenge for modern researchers.

“…This formation was the subject of several studies mainly dealing with its facies characteristics, palaeoenvironmental setting, diagenetic history, sequence stratigraphy and reservoir properties (e.g., Masse et al, 1997 andvan Buchem et al, 2002;Gre´selle and Pittet, 2005;Yose et al 2010;Rameil et al, 2010;Skelton and Gili, 2012;Granier and Busnardo, 2013). Most of these researches were focused on the Late Aptian unconformity at top of the Shu'aiba Formation and its geological and reservoir aspects including the nature, development and controls on reservoir evolution (e.g., Immenhauser et al, 2000;Rameil et al, 2012;Maurer et al, 2013).…”

ABSTRACT:García-Mondéjar, J., Fernándes-Mendiola, F. and Owen, H.G. 2015. The OAE1a in Cuchía (Early Aptian, Spain): C and O geochemistry and global correlation. Acta Geologica Polonica, 65 (4), 525-543. Warszawa.C-isotopes, TOC and O geochemical data from the lower Aptian Cuchía section in the western BasqueCantabrian basin (BCB) allow an accurate delimitation of the OAE1a-equivalent and its geochemical Menegatti´s segments, a detailed δ 13 C carb correlation with regional and interregional sections, and a high-resolution construction of TOC and bulk-rock δ 18O carb curves and their interpretation. The δ 13C carb values range from -2‰ and +4‰ (VPDB). They agree with previous data from the eastern BCB sections (Aralar) confirming the ammonite age of the OAE1a in the Basque-Cantabrian basin: Deshayesites forbesi, Deshayesites deshayesi, and Deshayesites deshayesi-Dufrenoyia furcata transition Zones. Interregional δ 13 C carb correlation with pelagic (Cismon, Italy, and Mid-Pacific Mountains, DSDP Site 463) and neritic (Roquefort-La Bédoule, France) core sections, reveals a common profile of a wide negative excursion characteristic of the OAE1a. It consists of a double trough separated by a flat relative maximum, with two negative spikes in the upper trough of neritic sections. TOC absolute values range from 0.12% to 1.37%. Segments of the TOC curve with persistent low values closely correspond with descending segments of the δ 13 C carb curve, and are attributed to lesser organic productivity in the BCB. Detailed bulk-rock δ 18O carb data (-5.71‰ to -1.05 ‰ PDB) and variation curve show two main positive O-isotope shifts and three minor positive inflections, within a general negative trend characteristic of the OAE1a. The two major positive shifts correspond to both shallowing upwards sequences and the lowermost can be related to a eustatic sea level fall. Independent interregional correlation of the O-isotope shifts with C-isotopes supports their interpretation as punctuating colder events within a general warming trend.
