Plate Tectonic Setting: Global Events 1. Permo Triassic Opening of Neo Tethys

Continental Fragments Split from North Africa

2. Early – Late Cretaceous

Opening of the Atlantic Ocean

A dextral transform fault extended into Africa, creating a strike-slip

faulting Central African Shear Zone (CASZ) and related transtensional

basins in Central Africa.

3. Middle – Late Eocene

Central African Shear Zone (CASZ)

Assessment of Undiscovered Oil and Gas Resources of the Sud Province, North-Central Africa; USGS

USGS estimated mean volumes of 7.31 billion barrels of oil, 13.42 trillion cubic feet of gas and 353 million barrels of natural gas liquid.

Area contains 113 oil fields (18 in Chad and 95 n Sudan).

Producing fields and recent discoveries limited to Cretaceous-Tertiary rift basins

Resource estimate does not include the Anza basin and the Tertiary discovery the Lake Albert basin of Uganda.

Collision of Eurasian and African plates Creation of NW-SE compressional stress Induction of NE-SW tensile stress

Activation of East African Rift (EARS) Plat Margin

Oil

Offset of rift segments of the Central African Rifts System is also opposite to the direction of actual

displacement across the Central African Shear zone (CASZ) – evidence for a transform fault
