The Paleocene benthic foraminiferal zonation of the Umm Er Rhadhuma Formation from borehole (K.H 12/7), South Anah City (Western Iraq), has been re-studied and re-analyzed precisely based on large foraminifera (LBF). They are represented by two biozone Rotorbinella hensoni Partial Range Zone, recorded Lower middle parts Lockhartia praehaimei Zone determined Uppermost this unit, dated to be Sela...

Abstract This paper provides an understanding of the sedimentary-tectonic evolution Cenozoic strata El Habt and Ouezzane Tectonic Units (Intrarif, External Rif) in Morocco. New data provide information about depositional architecture enable a correlation Rif Morocco with that Betic Cordillera Spain Tunisian Tell, which new insights for hydrocarbon exploration region regarding possible source, r...

Emerging evidence suggests that U-Pb and Lu-Hf ages of sedimentary apatite group minerals are often younger than their biostratigraphic ages. However, dating exquisitely preserved carbonate fluorapatite (CFA) is rare. The Upper Cretaceous/Paleogene marine rocks the Moroccan High Atlas host phosphate-rich sediments bracketed by calcareous nannofossil Zones (NP4-NP9) late Danian to Thanetian age....

Accurately deciphering periodic variations in paleoclimate proxy signals is essential for cyclostratigraphy. Classical spectral analysis often relies on methods based on (fast) Fourier transformation. This technique has no unique solution separating variations in amplitude and frequency. This characteristic can make it difficult to correctly interpret a proxy’s power spectrum or to accurately e...

Sediments recovered at ODP Site 1262 on Walvis Ridge (eastern South Atlantic Ocean, paleodepth ∼2500–3000 m) offer an opportunity to look into the nature and cause(s) of the benthic foraminiferal turnover across the Cretaceous/Paleogene (K/Pg) boundary at abyssal depths at a location relatively remote from the location of the asteroid impact on the Yucatan peninsula. Late Maastrichtian assembla...

Uppermost Maastrichtian benthic foraminiferal assemblages (N63 Am) are diverse, indicating mesotrophic conditions in lower bathyal DSDP Hole 465A (Hess Rise, central North Pacific), in 4 lower bathyal land sections in central-East and Northeastern Mexico, and in the upper to middle bathyal Agost section (Tethys area, Southeastern Spain). They indicate more eutrophic conditions in lower bathyal ...
