This work was designed to understand the paleoenvironmental conditions during ‎Cenomanian−‎ Turonian oceanic anoxic event 2 (OAE2) and its impact on the organic carbon-rich ‎accumulation in Abu Roash (F) carbonates through some organic and inorganic ‎geochemical results combined with microscopic examinations in two exploration wells ‎in the Abu Gharadig Basin, Egypt. Geochemical proxies indicated that AR-F is ‎marine environment is marine environment, ranging from deep sea to slope and deep ‎shelf, from the presence of large quantities of planktic forams and other marine ‎skeletal assemblages, including bivalves and echinoderms, with rare ostracods. The Ni ‎and V geochemical proxies, confirmed that these facies were mainly found in low ‎oxygen environments contributing to the preservation of organic matter. An Rb/Sr ‎ratio of less than 0.1 and the dominant presence of warm-water plankton species (i.e., ‎Globigerinoides sp.) together with a large number of primary producers (i.e., algae and ‎dinocysts) suggested warm climatic conditions during OAE2. These warm climatic ‎conditions could be attributed to increased organic productivity and preservation of ‎the water column. ‎
