“…As it is claimed by Hallam (2001), Kominz et al (2008), Miall (2010), and Ruban et al (2012), only further numerous inter-regional correlations of the available geologic records may refine our view of Phanerozoic eustatic changes. As a result, there were many other developments in the study of eustasy in the past two decades.…”

“…However, this hypothesis is, at least, reasonable and needs serious consideration. The above-mentioned uncertainties can be addressed adequately with multiple inter-regional correlations of changes in basin geometry (Hallam, 2001;Kominz et al, 2008;Miall, 2010;Ruban et al, 2012;Haq, 2014) and through geodynamic modelling (Müller et al, 2008;Conrad and Husson, 2009;Spasojevic and Gurnis, 2012;Conrad, 2013).…”

“…During the last two decades, our knowledge of global sea-level changes and their controls through geologic history has improved significantly (Embry, 1997;Abreu and Anderson, 1998;Hallam, 2001;Eriksson et al, 2005Eriksson et al, , 2013Haq and Al-Qahtani, 2005;Miall, 2005Miall, , 2010Miller et al, 2005;Catuneanu, 2006;Johnson, 2006Johnson, , 2010Haq and Schutter, 2008;Kominz et al, 2008;Müller et al, 2008;Coughenour et al, 2009Coughenour et al, , 2013Galeotti et al, 2009;Lovell, 2010;Catuneanu et al, 2012;Ruban et al, 2012;Spasojevic and Gurnis, 2012;Haq, 2014). This has been facilitated by achievements in various disciplines of geology (Fig.…”

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 matches the reconstruction of Farouk and El-Sorogy (2015) and their interpretation of the possible controls much better than in the case of the curve of Haq and Al-Qahtani (2005). Finally, Ruban et al (2012) established the global regressive episode in the late Danian and the global transgressive episode in the latest Danian-early Selandian. This also matches what was found in the regional record of the Western Desert by Farouk and El-Sorogy (2015).…”

“…One was developed first by Miller et al (2005) on the basis of very accurate data from the New Jersey margin of North America, and its slightly different version was published by Kominz et al (2008). Another curve was proposed by Ruban et al (2012) on the basis of the global correlation of transgressions and regressions.…”

Micropalaeontological and isotopic analyses of the middle Palaeocene succession at Gebel Nezzi (Luxor, Egypt): Implications for eustatic changes

et al. 2018

Gebel Nezzi (Upper Nile Valley, Egypt) was chosen to study the middle Palaeocene planktonic foraminiferans, nannoplankton contents, benthic foraminiferans, and stable isotopes to provide additional information into sea‐level changes. Two negative excursions are recorded that are associated with a sharp change in palaeoenvironmental conditions, representing significant global palaeoceanographic, palaeoclimatic, and eustatic events observed at other sites around the world. They are characterized by a drop in total foraminiferal abundance associated with a drop in the type, species richness, frequency, and diversity of foraminifers. The first negative excursion of −0.6‰ δ13C and −0.5 δ18O occurs during the Late Danian Event (LDE) almost near the upper part of the planktonic foraminiferal P3a Subzone and within the calcareous nannofossil NTp8A Subzone at the top of the lower third of Chron C26r. It is dominated by shallow‐water benthic foraminiferans of the Neoeponides duwi biofacies. The Danian‐Selandian boundary lies directly above the LDE within the top of the nannofossil Zone NP4, and within the planktonic foraminiferal Subzone P3b with significant increases in angular morozovellids associated with the earliest Cenozoic hyperthermals. The second negative excursion of −0.6‰ δ13C and −2.2 δ18O occurs near the top of the Dakhla Formation and is dominated by the benthic foraminiferal Bulimina farafraensis biofacies within the upper part of the calcareous nannofossil NTp9 Subzone and upper part of the planktonic foraminiferal P4a Subzone. These negative excursions associated with a well‐known falling sea level and are an important tool for regional correlation. Fluctuations in the foraminiferal population, benthic biofacies, δ 13C and δ18O isotopes and carbonate content reflect three fourth‐order transgressive–regressive (T–R) sequences response to eustatic changes in the Egyptian stable tectonic shelf.
