Location, schematic cross-section, and lithostratigraphy of the “A field”. a Location of the A field, indicated by a yellow star. b Stratigraphic outline of the Upper Cretaceous succession in the Abu Dhabi to Dubai area (modified from Al-Zaabi et al. 2010 and Yamamoto et al. 2016). The stratigraphic interval examined in this study is indicated (red square). A, rudist-bearing porous limestone facies comprising mainly rudist-bearing rudstone and floatstone with a matrix of grainstone–packstone–wackestone; B, organic-rich dark-gray mudstone–wackestone–mudstone, partially stylolitized; C, siliciclastic sediments extensively filling the remaining accommodation space in the preceding intrashelf basin; D, platform facies comprising argillaceous limestone in central and western Abu Dhabi; E, dark grayish-brown to black shale, locally interbedded with dense limestone. Note that the facies C, D, and E were not deposited in eastern Abu Dhabi, due to uplift of this area. c Schematic cross-section of the A field (orange color denotes limestone-shoal facies, yellow upper-slope facies, green lower-slope facies, and blue basinal facies). Diagram modified from Neo (1996)
