The Maastrichtian section within Oued Lahouar offers a unique opportunity to investigate
sedimentological characteristics and depositional processes in this stratigraphic unit. This study presents a
comprehensive sedimentological description of the Maastrichtian section in Oued Lahouar, focusing on
lithology, sedimentary structures, and depositional environments. Field observations, sedimentological
analysis, and petrographic examinations were conducted to unravel the sedimentary history of the
formation. The study emphasizes different fossils, trace fossils and carbonate nodules identification.
Sedimentary structures such as cross-bedding, ripple marks, and bioturbation provide insights into the
depositional dynamics and paleoenvironmental conditions. Interpretations suggest deposition in a shallow
marine setting characterized by fluctuating energy conditions. Additionally, the presence of fossil
assemblages aids in paleoenvironmental reconstructions and correlation with regional stratigraphy. This
sedimentological study contributes to a better understanding of the Maastrichtian sedimentary processes
and paleoenvironments in the Oued Lahouar area, shedding light on the geological evolution of the region
during the Late Cretaceous period.
