This Sheet Description describes the Quaternary and solid geology of the Mirfa 1:100 000 scale geological map. The Mirfa district includes a strip of the UAE mainland along the Arabian Gulf coast from Thumayriyah Island in the west and Mirfa in the east, including the islands of Marawah and Jananah. This district is particularly important for its exposures of the Miocene bedrock, notably the section at Jebal Momiya, near Mirfa, a key palaeontological site from which many vertebrate remains have been found, and Quaternary marine sediments on the island of Marawah, including type site for the Marawah Formation. The oldest rocks in the area are the Miocene rocks of the Shuwaihat and Baynunah formations which form a series of northwest to southeast trending ridges and headlands rising up above the coastal plain, and underlie much of the southern inland part of the sheet. The Shuwaihat Formation typically comprises a number of cyclical sequences deposited in a mixed aeolian-fluvial-sabkha environment. It is overlain by the Baynunah Formation with a characteristic basal bone bed overlain by fluvial lacustrine sediments. Quaternary sediments are present throughout much of the area. The Ghayathi Formation, moderately cemented carbonate-dominated palaeo-dune sandstones, occurs as isolated areas of outcrop resting on Miocene bedrock mostly in the southern part of the district. On the coast, deposits of the Abu Dhabi Formation are found in the subtidal, intertidal and supratidal zones, and forming extensive spits, bars and strand-plains. Inland of the coastal spit-bar complex are extensive areas of continental sabkha. Offshore, the island of Marawah is comprised of older Quaternary marine rocks of the Marawah and Fuwayrit formations.
