Depositional model for the Lower–Middle Miocene succession in the Abu Rudeis–Sidri Field, showing interpreted depositional environments, distribution of benthic foraminiferal biofacies, and representative benthic taxa across a generalized shelf-to-slope transect. The model illustrates three depositional phases: (1) inner shelf (Nukhul Formation), (2) middle to upper shelf/slope (Lower Rudeis Formation), and (3) restricted lagoon (Kareem Formation), placed within a paleobathymetric framework. Foraminiferal depth ranges are based on81,96 and115.
