“…The upper part of the Khanasir Limestone Member was given a Santonian-Campanian age by El-Asa'ad who referred the Hajajah and Lina members to the Maastrichtian. The El-Asa'ad stratigraphic framework was agreed by El-Nakhal and El-Naggar (1994) and retained by Sharland et al (2001).…”

The Aruma Formation is a predominantly carbonate lithostratigraphic unit of Late Cretaceous age that crops out in Saudi Arabia. It consists of three members: from base to top they are Khanasir Limestone Member, Hajajah Limestone Member, and Lina Shale Member. In order to establish a stratigraphic revision of the Formation, a reference section near Al Kharj, southeast of Riyadh in central Saudi Arabia, was logged and a hierarchical organization of the depositional sequences established. The Aruma corresponds to four third-order cycles bounded by erosional unconformities. Integrated biostratigraphical data mainly based on ammonites, nannoflora, rudists, and larger foraminifera point to a Maastrichtian age for the Khanasir and Hajajah members, and a Paleocene age for the Lina Member. Regional stratigraphic correlations were established within the outcropping Aruma Formation in Saudi Arabia. Biostratigraphy and sequence stratigraphy allowed a correlation framework to be proposed between the Aruma and the Qahlah and Simsima formations of the United Arab Emirates and the Oman Mountains, and with the Sharwayn Formation of the Hadramawt and Dhofar. The high-resolution stratigraphic scheme established for the Aruma Formation in Saudi Arabia is expected to be useful for subsurface correlations and in petroleum exploration.

“…El‐Asa'ad (1983b) proposed a Coniacian age for the lowermost part of the Khanasir Member, based on the occurrence (but with no illustration) of the ammonite Tissotia tissoti (Peron) (Figure 10). The upper part of the Khanasir Member was assigned a Santonian‐Campanian age, based on the presence of the rudist Eodictyoptychus arumaensis (El‐Nakhal & El‐Naggar, 1994; Sharland et al, 2001; Skelton & El‐Asa'ad, 1992). However, other workers (Le Nindre et al, 1990; Powers et al, 1966; Vaslet et al, 1988, 1991) proposed a Late Campanian age to its lower part based on record of the ammonite Libycoceras acutodorsatus (Figure 10).…”

Lithofacies characteristics, depositional architecture (facies tracts and depositional sequences), stable isotopes (δ 18 O and δ 13 C), and 87 Sr/ 86 Sr ratios were analysed from the Aruma Formation at the Khashm Buwaibiyat section (north-east Riyadh, Saudi Arabia). The Aruma Formation consists of three formal members (base to top), Khanasir, Hajajah, and Lina members. Based on 87 Sr/ 86 Sr and δ 13 C data, the lower age of the regionally distributed Aruma Formation (Khanasir Member) is now proposed as Late Campanian. This age assignment is supported by the identification of a distinct δ 13 C negative excursion (=Epsilon Event; Upper Campanian), and a globally conformable range of 87 Sr/ 86 Sr values (0.707604-0.707703). Additionally, a review of previous fauna (ammonites and nannofossils) also favours this age assignment. The 87 Sr/ 86 Sr values (0.707817-0.707848) from the upper part of the Hajajah Member reflects a Late Maastrichtian signature as also noted by the presence of a longterm δ 13 C decrease. Additionally, based on lithofacies and depositional architecture for the Aruma Formation, nine facies types are identified. These are grouped into four facies associations (restricted peritidal, lagoon inner ramp, shoal transgressive lag, and coral reefs), reflecting four third-order depositional sequences (transgression-regression cycles). These reflect strong influence of both eustatic sea-level rise and regional tectonics (resulting in widespread unconformities and long-time gaps). The shallowing and deepening of the sea level is inferred using sequence stratigraphy (system tracts) and lithofacies variations. This data suggests a gradual rise in sea level from the Upper Campanian to the Maastrichtian with an intervening fall around the Campanian-Maastrichtian boundary.
