Sea-Level and Environmental Change Across the K/Pg Boundary and PETM Event on the Southern Tethyan Margin: Foraminiferal and Sequence-Stratigraphic Evidence from Egypt
Randomized trial reconstructs paleoenvironmental changes during significant geological events in Egypt, suggesting local influences on global patterns.
Key Points
The study aims to reconstruct the paleoenvironmental and sequence-stratigraphic evolution across significant geological intervals in Egypt.
Integrated analysis of lithostratigraphy and microfacies in Esh El-Mellaha sections.
Examination of benthic foraminiferal assemblages and paleodepth estimates.
Identification of erosional surfaces and depositional sequences across Cretaceous-Paleogene intervals.
Identification of two major erosional surfaces, including a significant hiatus at the K/Pg boundary.
Foraminiferal assemblages indicate contrasting ecological responses across K/Pg and PETM sequences.
Refinement of the Maastrichtian-Ypresian framework with five depositional sequences showing modification by local tectonism.
