Abstract

Summary

Multiple deep oil shale deposits were discovered in Jordan in the last two decades. A series of investigations were initiated in the attempt to better understand their characteristics and depositional environments. In this study a succession of Selandian-Ypresian oil shales from the Azraq-Hamza Basin in the central-east Jordan is examined. These are mainly composed of bituminous marl intercalating with chalky limestones. The marls in the upper part of the Ypresian are highly silicified and rich in radiolarians. Petrographic studies revealed 5 major microfacies types. A remarkable negative excursion in the δ13Corg and δ13Ccarb marks the Paleocene-Eocene boundary. The δ13Ccarb are independent from potential organic matter preservation vs. oxidation episodes. Total organic carbon content (TOC) varies throughout the section and in parts is affected by the hypersalinity of the water column.
