The United Arab Emirates (U.A.E.) is located on the eastern Arabian shelf, bounded on the northwest by the Qatar-South Fars Arch and on the east and northeast by the foreland basin and the adjacent foreland fold-and-thrust belt of Oman. Two passive-plate-margin basins were developed in the area, the northern Rub Al Khali basin and the Ras Al Khaimah basin. Since the Permian, a variety of sub-basins, separated by depositional and tectonic highs, have formed, filled, and been buried, but the style of sedimentation has been maintained. The Upper Permian to Holocene rocks and sediments of the U.A.E. consist mainly of epeiric shelf carbonates, associated with minor evaporites and clastics, reflecting major cycles of transgression and regression. These sediments were deposited on the eastern margin of the Arabian Shield, which lay along the southern margin of the Tethys Ocean during the Mesozoic and Cenozoic eras. Sedimentation patterns were controlled by prominent regional structural features, epeirogenic movements, and/or sea-level fluctuations. Abundant oil and gas reserves have been proved in the Mesozoic rocks of the U.A.E., and are contained in the shallow-water carbonates of the Jurassic (Araej and Arab formations) and the Cretaceous (Thamama Group, Mishrif, and Simsima formations). Reservoirs are sourced by deep-water bituminous shale and argillaceous limestones and sealed by evaporites, dense limestones, and shales. The distinctive sedimentologie and structural style, together with the development of source-reservoir-seal, has made the U.A.E. one of the world’s richest Mesozoic oil habitats. Detailed studies of the occurrences and distributions of the factors controlling hydrocarbon distribution are important in the understanding of local oil fields and future plays.

Middle East Models of Jurassic/Cretaceous Carbonate Systems
This volume will interest tectonic modelers, stratigraphers, sedimentologists, and explorationists. It is the product of the international conference of “Jurassic/Cretaceous Carbonate Platform-Basin Systems, Middle East Models” that was convened in December 1997 jointly by SEPM (Society for Sedimentary Geology) and the United Arab Emirates University in Al Ain, United Arab Emirates. The twenty-three papers present new data and interpretations arranged in three sections: 1) sequence stratigraphy, cyclostratigraphy, chronostratigraphy, and tectonic influences, 2) depositional and diagenetic models of carbonate platforms, and 3) hydrocarbon habitat and exploration/development case studies. New tectonic models of the Arabian Basin, new stratigraphic and sequence stratigraphic reference sections, new geochemical and source rock data, and new reservoir data are presented. New geologic models make this set of papers relevant to geoscientists working outside of Arabia also.
