Tuwaiq Mountain and Hanifa Formations in Oman

The Middle Jurassic Tuwaiq Mountain Formation in Oman is only present in the WNW, as a result of truncation related to uplift and subaerial exposure of the eastern plate margin. The Tuwaiq represents a carbonate shoal complex, which prograded from eastern Oman towards the west into an intra-shelf basin, located in western Abu Dhabi and Qatar. This formation yields good reservoir carbonates and is sealed by deep-water aphanitic limestones.
