oa Microbial Dolomite of the Coastal Sabkha of Abu Dhabi as a Modern Analogue of the Triassic Dolomite Reservoirs of the Northern Parts of the Arabian Plate

Microbial dolomites have been fully documented in lagoonal and sabkha sediments from different parts of the world. Detailed textural characterization, using SEM coupled with Energy Dispersive X-ray (EDX), of three deep cores (down to six meters) and fifty surface samples from the intertidal and supratidal zones of the coastal sabkha of Abu Dhabi indicate that dolomite constitutes up to 50% of the bulk sediments.
