The Simsima Formation (lower Upper Maastrichtian) is a shallow–water carbonate that crops out in eastern United Arab Emirates along the northwestern border of the Oman Mountains. Its thickness ranges in this region from 30 to 80 m. From detailed sedimentological and petrographical analysis, various microfabric types and eight sedimentary fades are recognized in the Simsima Formation. These microfacies are arranged according to their frequency and collected into three groups as follows: packstone group (orbitoidal packstone, bioclastic packstone, algal packstone, and plank tonic foraminiferal packstone); boundstone group (milleporid, coral, and algae), and dolostone, which consists mainly of dolomitized limestone. The Simsima Formation in this study can be subdivided into two new members, called here the lower member and the upper member, each with a distinct character and considerable vertical and horizontal distribution.

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.
