About eighty rock samples collected from the Jurassic sediments exposed at Wadi Milaha (1400 m thickness), near Ras El Khimah Emirate, have been subjected to a comprehensive stratigraphic, palynofacies, microfacies, structural setting and hydrocarbon potentiality studies. The Jurassic rocks could be classified into three informal units of the Musundam Group (Lower, Middle and Upper units) which represented by oolitic limestones, algal lime-grainstone and oolitic lime-grainstone respectively. This microfacies association reflects near-shore to shallow marine depositional environment. The studied carbonate shelf rock units define a huge culmination sheet represented by a large asymmetric broad anticlinal fold that verges to the east. This anticline is intensively dissected by several parallel NNW-oriented thrust faults that dip towards the east forming an imbricate structural style. This structure configuration would greatly favor the reservoir potentiality of the Jurassic rocks. Total organic carbon for the Jurassic sediments ranges from 0.05 wt% to 7.70 wt% with average 0.73 wt% indicating fair to excellent source rock richness. The Jurassic source facies is typically shallow carbonate platform as indicated by the unimodal distribution of n-alkanes. The organic matter of the Jurassic sediments is marginally mature (at the beginning of catagenesis) as indicated by the high bitumen content (0.01%-0.1%).
