“…In contrast, the WA-3 section is situated within biozone UC-20b, recognized primarily based on the first occurrence [15]. Moving to the KAS-1 section, a hiatus is observed starting from the UC-20a, UC-20b, and UC-20c biozones, with the appearance of UC-20d marked by the presence of M. prinsii [14,17]. Another unconformity is noted as NP0 and NP1 are absent, and the successions show reworked species within the biozone NP2 [41].…”

“…Chronostratigraphically, the formational boundary between the Wadi Shallala and the Umm Rijam Chert Limestone in Wadi Shallala indicated regional paleoenvironmental changes in Jordan, which were closely correlated with neighboring countries like Egypt. In a study conducted by Alhejoj [17], they examined foraminiferal assemblages from the upper Maastrichtian to the middle Eocene succession in Jabal Ghuzayma. Using qualitative and quantitative analyses, they identified nine planktonic biozones spanning the upper Maastrichtian to the middle Eocene, along with two significant time gaps between the Paleocene/Eocene (P/E) and Cretaceous/Paleogene (K/Pg) unconformities.…”

Local geological and tectonic processes have been pivotal in shaping the diverse sedimentation patterns observed in Jordan, forming sub-basins characterized by elevated organic matter content (TOC). This study aims to characterize the Maastrichtian basin, focusing on sedimentation rates using calcareous nannofossils and understanding paleoecological and paleo-oceanic conditions. It offers insights into the paleoenvironmental factors impacting oil shale deposition in the late Maastrichtian–Paleocene period. It employs classical biostratigraphical, semi-quantitative, and statistical methodologies to achieve its objectives of age determination and paleoecological insights. A total of 116 smear slides from two sites were obtained: the first, consisting of WA-1 (23 samples), WA-2 (18 samples), and WA-3 (11 samples), and the second, with 60 samples. Notably, the sites exhibit varying topography. WA-1 and WA-2, situated at lower elevations, have the highest Total Organic Carbon (TOC) levels, while areas with higher elevations in section four are visually identified by a light color. The study revealed varying patterns of calcareous nannofossil richness in the two investigated sites. These patterns were instrumental in defining biozones, with the utilization of marker species such as Lithraphidites quadratus, Micula murus, Micula prinsii, and Cruciplacolithus tenuis. Chronologically, these sections were classified as Maastrichtian–Paleogene, encompassing the following biozones in sequential order: UC-20a, UC-20b, UC-20c, UC-20d, and NP-2. Furthermore, the study identified two hiatus intervals, observed in sections WA-1 and KAS-1. The absence of certain biozones in the analyzed sections suggests that these sections correspond to distinct geological blocks within the basin, underscoring the role of tectonic forces during the deposition period. The sedimentation rate initially commenced at low levels but gradually increased due to topographic alterations. Notably, the biozone UC-20c demonstrated a clear trend toward warming and enhanced nutrient availability. In this context, the abundance and diversity of species were associated with increased continental influx into the sub-basin, resulting in rising nutrient levels and the number of calcareous nannofossils. This study enhances the understanding of the local and global effects such as tectonic and climates of the continuity of basins by deciphering calcareous nannofossil patterns and their correlation with sedimentation factors.

“…During the early middle Miocene, uplift was triggered along the mountainous backbone of Palestine (Steinberg et al, 2010;Barabasch et al, 2019;Alhejoj et al, 2020). The transpression along the north-south sinistral strike-slip of the Levant (NW boundary of the Arabian Plate) caused a strong uplifting of Mount Lebanon during the late Miocene, which gradually closed the eastern siliciclastic sources of the Arabian plate in northern Lebanon.…”

Carbonate rocks are gaining more importance as natural building stones, karst aquifers, and hydrocarbon reservoirs in many parts of the world, including the giant fields of the Middle East (Burchette, 2012). According to Ehrenberg and Walderhaug (2015), more than 50% of all hydrocarbon reserves are hosted in carbonate rocks. Various physico-chemical and biological processes are associated with the formation and modification of carbonate rocks, leading to dramatic changes in their storage capacity, petrophysical, elastic and textural properties (
