Anisian δ13C profiles of carbonates from Romania, Vietnam, and South China. a North Dobrogea, Romania (Atudorei et al. 1997); b North-Central Coast region, Vietnam (this study); c Bianyang section, Nanpanjiang Basin, South China (Sun et al. 2012); d Guandao II section, Nanpanjiang Basin, South China (Sun et al. 2012); e Guandao section, Nanpanjiang Basin, South China (Payne et al. 2004). The vertical red double arrows indicate the interval represented by the studied carbonate succession in Vietnam. The small horizontal arrows indicate the basal horizon of the Bithynian δ13C decrease followed by the interval of prolonged (Bithynian–Pelsonian) stability or gradual decrease in values, as reported from South China and Romania. Abbreviations: Aeg, Aegean; Bith, Bithynian; Illy, Illyrian; Lad, Ladinian; Olen, Olenekian; Pels, Pelsonian
