Study Notes
Jurassic Marine Transgression
- The peak of the Jurassic marine transgression in the Northern Western Desert is represented by the Khatatba Formation.
Paleozoic Section and Unconformity
- A higher unit that unconformably overlies the lower unit with abundant shale beds in the Paleozoic section is the Dakhla Formation.
Thickness of Paleozoic Section
- The approximate thickness of the Paleozoic section in the Siwa area of the Western Desert is about 1,800 meters.
Early Cretaceous Deposits
- A marine shale unit followed by massive fluvial sand bodies was deposited during the Early Cretaceous cycle known as the Albian cycle.
Cambrian Shale Units
- A lower unit with abundant shale beds, dated as Middle Cambrian, was intersected in the Bahariya-1 exploratory well during the drilling operations.
