Title: A Permian-Triassic Boundary in the Middle East: A Review
Abstract: The Middle Permian - Early Triassic Khuff Formation occurs throughout the subsurface in the Middle<br>East and is believed to contain the biggest gas reserves in the region. Along the epeiric Arabian<br>platform shallow-water carbonates and evaporites prevail in the northern and central part and pass<br>southward in argillaceous carbonates and siliciclastics. In eastern direction shallow-water carbonates<br>pass in deep marine deposits of the Neo-Tethys. Outcrops in Saudi Arabia, Iran, UAE and Oman<br>provide important analogue data for subsurface geologic models.<br>The Permian-Triassic Boundary (PTB) event, about 251 million years ago, was the time of the most<br>severe mass extinction during the Phanerozoic that heavily affected marine and terrestrial ecosystems.<br>Sedimentary rocks of the Khuff Formation and equivalent formations in the Middle East yield abrupt<br>litho- and biofacies changes which are believed to be the result of events associated with Permian-<br>Triassic Boundary (also called end-Permian mass extinction in the literature) and the Early Triassic<br>recovery interval.
