Maps, diagrams and photographs of the Abu Dhabi (UAE) coastal sabkhas with their evaporite assemblages of anhydrite, gypsum, and dolomite, their flanking cyanobacterial (algal) flats, and seaward ooid shoals and barrier islands Christopher Kendall 1/1/2004 Coastal Carbonate & Evaporite Settings Click on Galleries to return to SEPM Sequence Stratigraphy photo galleries or on SEPM Sequence Stratigraphy for Strata home page.kendall@sc.edu

This gallery of photographs, maps and diagrams is focused on the United Arab Emirates (U.A.E.) shoreline. It is linked to a guide to the Holocene shallow water carbonate and supratidal evaporite tract that lines the southern coastal embayment of the Arabian (Persian) Gulf. This consists of seaward reefs, barrier islands and tidal flats associated with the carbonate barrier Islands of Abu Dhabi, Sadaiyat, Halat Al Bahran, and Abu Al Abyad, the peninsulas of Dhabaiya and Jebel Dhanna, and the Khor Al Bazam lagoon. Between the barrier islands are ebb tidal deltas that are the site of ooid shoals. In more protected but high energy coastal terraces are the sites of grapestone accumulations. The upper portion of many of the protected tidal flats is the site of the growth of cyanobacterial mats (blue-green algal and/or stromatolite) mats. These in turn are flanked landward by supratidal gypsum and anhydrite rich flats, the sabkha. As with similar sedimentary sequences from the geological section in the subsurface of the Arabian Gulf, and elsewhere in the geological record, the sediments of this coastal region pass landward into a continental facies and seaward into a basinal facies.
