Geological Background
The Albert Graben is part of the Western branch of the East African Rift System. It stretches from the border between Uganda and Sudan in the north, to Lake Edward in the south. Rifting is interpreted to have started during Early Miocene approx. 17 million years ago.
Geological and geophysical data indicate that the Graben has gone through extension and compression episodes resulting into a variety of structures. Deformation and prevalence of flower structures in the shallow sedimentary section in some basins in the Graben indicate that the neo-tectonic processes are compressional. The Graben is characterized by highly asymmetrical deep tertiary basins that are separated by complex transfer zones
