Depositional environment of the Upper Cretaceous oil shales in the Negev Desert, Israel: Geochemical constraints based on trace elements and stable isotopes

A study in inorganic geochemistry from the Campanian (Mishash Formation) - Maastrichtian (Ghareb Formation) transition of southern Israel was done to provide insights into the inference of foraminiferal assemblages, water column-oxygen levels, trace metal enrichment on a high-productivity seafloor. A series of high-resolution approaches in inorganic geochemistry applied on a 50 m sequence in the Efe`s syncline of the Negev desert. A conceptual model of the deposition history was developed.
