WANCE:A possibly Volcanism-Induced Ediacaran Carbon Isotope Excursion
文献摘要：
Four carbonate carbon isotope(δ13Ccarb)excursions are recognized in the Ediacaran Doushantuo Formation in South China,the genesis of which remains disputed.Whereas three of theseδ13Ccarb excursions possibly record secular biogeochemical variations,the other one,namely Weng'an neg-ative carbonate carbon isotope excursion(WANCE)with an age of ca.620 Ma occurs mainly within the northern Yangtze Platform.In this study,a SIMS U-Pb age of ca.620 Ma was documented from conti-nental rift volcanism within the adjacent South Qinling terrane.Its temporal overlap with WANCE suggests a possible causal link.Volcanism-induced seafloor uplift may have prompted DOC oxidation in surficial oxygenated oceans,inducing the occurrence of WANCE.
