Palynological analysis of these sediments is dominated by marine microplankton. The basal Izhara was found barren of index palynomorphs. Four informal dinoflagellate cyst assemblage biozones embracing the interval from Bajocian to Early Callovian are defined as follows: Mancodinium semitabulatum-Pareodinia ceratophora Assemblage Zone I (Early Bajocian), Gonyaulacysta pectinigera-Escharisphaeridia pocockii Assemblage Zone II (Late Bajocian), Ctenidodinium continuum-Dichadogonyaulax sellwoodii Assemblage Zone III (Bathonian), and Chlamydophorella ectotabulata-Rhynchodiniopsis cladophora Assemblage Zone IV (Late Bajocian-Early Callovian). These assemblages resemble those reported from Jurassic deposits elsewhere in the circum-Mediterranean region. The palynofacies and organic matter of these formations are almost exclusively of marine ...

S&T are considered to be key factors contributing to achieving sustainable development, prosperity and economic growth of marine resources in Mediterranean and North African. The exchange of expertise will enable scientists to carry out research aimed at supporting the implementation of the sustainable development of marine resources. In collaboration with a strong EU partnership, FORCE FP7 project considers a successful capacity building model to fill Scientific and technology gaps as means of increasing sustainable yields. Also, FORCE will promote the principles outlined in Horizon 2020.

Eleven samples were analyzed for their 87Sr/86Sr ratios. The results gave a chronostratigraphic range of Early Jurassic (Hettangian) to Late Jurassic (Oxfordian), with an overall age range of 202.4 Ma to 157.8 Ma. Maximum flooding surfaces MFS J10 to MFS J50 occur in the Izhara, Araej, and Hanifa formations. The organic matter in the carbonate sediments of the Izhara, Araej, and Hanifa formations was almost exclusively of marine algal origin dominated by marine microplankton. Organic matter obtained from the Izhara Formation was mature to over-mature kerogen type-III to IV, gas-prone to inert material (mean TOC 0.31%). In the Araej Formation, mature oil-prone and gas-prone kerogen type-II and type-III organic matter occurred in both the lower and upper Araej members (TOC 0.13-0.69%). The stylolitic limeston...
