f Influence of Oxic Diagenesis on Source Potential and Lithofacies Cyclicity: Insight from Cenomanian Natih-B Member Intrashelf-Basinal Carbonates, Oman

Investigation of core and outcrop samples of the Cenomanian Natih-B Member (North Oman) indicates that the different lithofacies present experienced rather different diagenesis shortly post-deposition. Petrographic, total organic-carbon (TOC), X-ray diffraction and stable-isotopic analyses have been employed to delineate the controls on early diagenesis and hydrocarbon source potential variability.
