“…3) is divided into the unconformity-bounded Sanya Formation, Meishan Formation, Huangliu Formation, Yinggehai Formation, and Ledong Formation (Zhao, 2010;Wu et al, 2014;Shao et al, 2017a;Shao et al, 2017b). The sedimentary facies and coral reef development (Zhao, 2010;Shao et al, 2017a, b;Wang et al, 2018) indicate that this succession encompasses two shallow-water cycles that are represented by (1) the Sanya Formation, Meishan Formation, and Huangliu Formation (Early Miocene to Late Miocene), and (2) the Yinggehai Formation to Ledong Formation (Pliocene to Pleistocene) ( Fig. 3).…”

On Xisha Islands, located in the South China Sea, the Neogene succession includes the unconformity-bounded Huangliu Formation that is 210.5 m thick in well CK-2 and formed almost entirely of dolostones. The diverse biota in the Huangliu Formation, which includes corals, algae, bivalves and foraminifera, indicates that the original carbonate sediments accumulated in water that was < 30 m deep. The dolostones are formed of various mixtures of low-and high-calcium calcian dolomite with limpid dolomite lining the walls of many cavities.The 18 O and 13 C stable isotopes suggest that dolomitization was mediated by slightly modified seawater. The 87 Sr/ 86 Sr ratios from the dolostones suggest that dolomitization took place ~9.4 and 2.3 Ma ago, with the age of dolomitization becoming progressively younger towards the top of the formation. "Island dolostones" like these, found on many islands throughout the Pacific Ocean and the Caribbean Sea, have commonly been linked to eustatic changes in sea-level with dolomitization taking place during lowstands, highstand, or transgressive phases. Data from the Huangliu Formation in well CK-2 suggests that dolomitization was associated with (semi-)continuous transgressive conditions that were controlled by the interaction of tectonic subsidence and eustatic changes in sea level.
