“…The low ratio of C 28 -steranes over C 27 -steranes in all samples can be attributed to a marine depositional environment with plankton-and/ or red algae-derived kerogen (Gagosian et al, 1983;Volkman, 1986). Similar results have been reported for the Ghadamis and Murzuq Basins (Harouda, 2004;Belaid et al, 2010) and the Berkine Basin in SE Algeria (Yahi et al, 2001 and 17) in some of the Triassic and Ordovician samples (Table 5), indicating a significant contribution of bacterial organic matter relative to planktonic and algal material. By contrast, Lower Tanezzuft samples show low values of these ratios (0.5 to 1.2), indicating the dominance of phytoplankton/algal-derived kerogen.…”

“…The determined ratios between 0.1 and 0.4 support an advanced maturity level and also indicate the variability of the samples investigated. Moretane/ hopane maturity ratios reported for Silurian source rocks in the Murzuq Basin (0.1-0.08: Belaid et al, 2010) are lower than those of samples from the Jifarah Arch analysed in this study, indicating higher thermal maturity of Tanezzuft shales in the Murzuq Basin.…”

“…"Hot shales" in the lower part of the Silurian Tanezzuft Formation are proven source rocks in the Murzuq and Ghadames Basins in Libya (Echikh, 1998;Echikh and Sola, 2000;Yahi et al, 2001;Belaid et al, 2009). The "hot shales" were recognized in three wells in the Jifarah Basin (E1-34, B1-8 and B1-23) and may extend across the basin into southern Tunisia.…”

“…The Algerian part of this basin (the Berkine Basin) was analyzed by Yahi et al, (2001) and Hallet (2002). The structure and hydrocarbon potential of the Murzuq Basin were discussed by Sikander et al, (2000), Hallet (2002) and Belaid et al (2010). These studies provided detailed information about the history of the basins, their sedimentary fills, the geochemical characteristics of potential source rocks, and probable migration paths and oil and gas accumulations.…”

“…More moderate magnitudes of Cenozoic erosion were therefore used here in modelling the four wells in the Ghadames Basin (see below). Yahi et al (2001) and Belaid et al (2010) presented excellent reviews of the geological history and geochemical characteristics of source rocks in the Ghadames and Murzuq Basins. They used onedimensional PetroMod software (Julich, Germany) to reconstruct the burial, thermal and maturity histories of key wells in these basins.…”
