This paper presents an overview of the distribution of the Infracambrian rocks within the Murzuq and Al Kufrah basins obtained by integrating existing data and new outcrop and subsurface data, and discusses the implications for the regional depositional setting and hydrocarbon potential.
In the Murzuq Basin the Infracambrian units comprise volcaniclastics, metasediments and fine- to medium-grained sandstones with an average thickness of 61 m, reflecting a proximal, clastic-dominated depositional system.
In the Al Kufrah Basin carbonate facies in Jabal Arkanu (eastern margin) indicate that the distal facies may become organic-rich. Interpreted seismic lines reveal Infracambrian graben systems similar to those found elsewhere that provide good hydrocarbon source rocks in petroliferous basins.

Global Neoproterozoic Petroleum Systems: The Emerging Potential in North Africa
Neoproterozoic successions are major hydrocarbon producers around the world. In North Africa, large basins with significant surface outcrops and thick sedimentary fills are widespread. These basins are now emerging as potential sources of hydrocarbons and are attracting interest from geological researchers in academia and the oil and gas industry.
This volume focuses on recent developments in the understanding and correlation of North African basin fills and explores novel approaches to prospecting for source and reservoir rocks. The papers cover aspects of petroleum prospectivity and age-equivalent global petroleum systems, Neoproterozoic tectonics and palaeogeography, sequence stratigraphy, glacial events and global climatic models, faunal and floral evolution and the deposition of source rocks.
The broader aim of this volume is to compare major environmental change, the emergence of life, the global carbon cycle and the implications for hydrocarbon exploration of well-studied Neoproterozoic successions worldwide.
