Syn-Rift Carbonate Platforms; Miocene-Recent Gulf of Suez

This 6-day field and classroom based course investigates the complex facies relationships found in rift basin carbonate platforms and provides insights into syn-sedimentary structural influences and changing depositional environments with rift basin evolution.

Based on the shores of the southern Gulf of Suez this course starts with a review and update on the processes of carbonate sedimentation using the natural laboratory of the nearby modern, shallow marine environments. Tectonostratigraphic models for carbonates are then investigated with a focus on rift basin environments. Concepts are reinforced and demonstrated in the field on world-class exposures of a exhumed Miocene carbonate platform. This enables potential reservoir facies to be studied in different structural settings (footwall, transfer zone etc.) and the change from marine to non-marine carbonate factories to be correlated with rift basin evolution. Final review lectures examine evaporitic to marine to lacustrine rift basin carbonates from Mesozoic and Cenozoic basins (SW and NE Atlantic, SE Asia and Red Sea-Gulf of Aden).
