The Middle Eocene Dammam Formation carbonates in the Saa area near the UAE-Oman border are divided into two lithofacies: grainstones and wackestones/packstones. The grainstones contain a new occurrence of N. hottingeri, a new subgroup of the N. partschi group along with Dictyoconides sp. benthic larger foraminifera, fragmented echinoids, algae, bryozoans, corals molluscs, bivalves and gastropods. The wackestones/packstones contain benthic foraminifera, miliolids, nummulites, ostracods, algae and many peloids. The ambient environment was intermediate depth marine. The grainstones were transported from shallow water areas into the deeper water, as olistostromes. The Saa carbonates are SBZ17 (Bartonian) age, based on the presence of N. hottingeri. The Saa section shares features of both the Priabonian calcarenites and Lutetian-Bartonian marly limestones of the Dammam Formation at the well-studied Gebel Hafit section, 25 km to the west. The Saa section complements the stratigraphic description of the Dammam Formation, representing a sequence that is poorly exposed at Gebel Hafit.

阿联酋-阿曼边境附近 Saa 地区的中始新世达曼组碳酸盐岩分为两种岩相：粒状岩和瓦砾岩/泥岩。该颗粒灰岩含新发生N. hottingeri，在新亚N. partschi组沿Dictyoconides SP。底栖较大的有孔虫、破碎的海胆类、藻类、苔藓动物、珊瑚、软体动物、双壳类和腹足类动物。wackestones/packstones 包含底栖有孔虫、miliolids、nummulites、介形虫、藻类和许多peloids。周围环境是中等深度的海洋。粒石从浅水区被运送到更深的水中，作为 olistostromes。根据 N 的存在，Saa 碳酸盐岩的年龄为 SBZ17（巴顿）。霍廷杰里. Saa 段在研究充分的 Gebel Hafit 段具有达曼组的普里亚博阶钙质岩和卢特阶-巴托阶灰岩的特征，位于西部 25 公里处。Saa 剖面补充了 Dammam 组的地层描述，代表了 Gebel Hafit 出露较差的层序。
