N2 - The Upper Carboniferous-Early Permian Haushi Group is equivalent to the Arabian Plate Megasequence 5 (AP5) and comprises Al-Khlata and Gharif Formations. Wireline sequence stratigraphic analysis from conventional wireline logs in the Dhofar Region, South Oman, has shown that Haushi Group composes of seven third-order system tracts. The Al-Khlata Formation is subdivided into two system tracts, a highstand system tract (HST) followed by a transgressive system tract (TST). The lower Al-Khlata Member is composed of aggrading facies of galciofluvial sand packages and diamictites reflecting an early stage of ice retreat, capped by transgressive fine sediments of the upper Al-Khlata Member. The upper part of the Haushi Group corresponds to the Gharif Formation and is subdivided into four systems in order, transgressive system tract (TST), highstand system tract (HST), transgressive system tract (TST), and finally, the lowstand system tract (LST). The lower Gharif Member deposited consecutively and shared the transgressive system tract (TST) with the upper Al-Khlata Member. This system tract ended with marine shales marking a maximum flooding surface. The middle Gharif reflects a highstand system tract (HST), which comprises progradational calcareous siliciclastics. A sequence boundary marks the end of this system. The upper Gharif Member represents a transgressive system tract in the bottom, shifting to a regressive lowstand system in the top sediment packages of Upper Gharif.
