f Anatomy of a World-Class Source Rock – Lower Silurian “Hot Shale” in the Kufra Basin (SE Libya) and Murzuq Basis (SW-Libya)

P146 Anatomy of a world-class source rock: Lower Silurian "hot shales" In the Kufra Basin (SE-Libya); and Murzuq Basin (SW-Libya) 1 The early Silurian in North Africa and Arabia was characterised by widespread deposition of organic-rich "hot" shales in Palaeo-depressions. The unit represents an important hydrocarbon source rock in the Murzuq Basin and other parts of northern Gondwana such as Algeria Jordon and Saudi Arabia. Presence or absence of the Silurian "hot shales" in the Kufra Basin is currently under debate and will decide about the basin's hydrocarbon prospectivity. The "hot shales" marker of the basal Tanezzuft has a wide
