δ ¹³C chemostratigraphy in the Lower–Middle Ordovician succession of Öland (Sweden) and the global significance of the MDICE

Carbon isotope records of the Middle–Upper Ordovician transition in Yichang area, South China

“…Up to now, at least seven striking ␦ 13 C positive excursion events have been recognized and named in the Middle and Upper Ordovician, including the MDICE (Middle Darriwilian), SAICE (Sandbian), GICE (earliest Katian), KOPE (early Katian), FAIRVIEW (early Katian), WAYNESVILLE (late Early Katian), WHITEWATER (earliest Late Katian), and GICE (Hirnantian) (Bergström et al, 2009(Bergström et al, , 2012. Among them, the MDICE has been widely recorded in many localities in Baltoscandia Ainsaar et al, 2010;Bauert et al, 2014;Calner et al, 2014;Lehnert et al, 2014), Siberia , South America (Buggisch et al, 2003;Albanesi et al, 2013;Sial et al, 2013), and possibly South China Zhang et al, 2010;Munnecke et al, 2011) and North America (Kaljo et al, 2007). The Guttenberg Carbon Isotope Excursion (GICE) of the earliest Katian has been documented from a considerable number of localities in North America (Young et al, 2008;Bergström et al, 2009Bergström et al, , 2010Bergström et al, , 2011 and South China (Bergström et al, 2009;Munnecke et al, 2011;Fan et al, 2013).…”

Carbon isotope chemostratigraphy and conodonts of the Middle–Upper Ordovician succession in the Tungus Basin, Siberian Craton

“…Relatively high ␦ 13 C values in the Volginian Stage seem to fit with the Mid-Darriwilian positive excursion (MDICE). The MDICE has a global distribution, being recorded in the Darriwilian interval of Baltoscandia (Ainsaar et al, 2007(Ainsaar et al, , 2010Calner et al, 2014), South America (Albanesi et al, 2013), North America (Leslie et al, 2011), and China (Schmitz et al, 2010). The correlation of the sequence boundary at the base of the Volginian Stage with the base of the Aseri Stage in Baltoscandia Kanygin et al, 2010b) is supported by the presence of the MDICE in the Volginian Stage in Siberia (Fig.…”

Lower–Middle Ordovician δ13C chemostratigraphy of western Baltica (Jämtland, Sweden)

“…In a recent study on the Tingskullen drillcore by Calner et al (2014), the entire suite of Ordovician 'orthoceratite limestone' from the island of Öland (southeastern Sweden) was assessed. The authors documented a significant positive ␦ 13 C excursion, spanning the upper Köpingsklint and lowermost Bruddesta formations (Fig.…”

“…All rights reserved. correlation (e.g., Schmitz et al, 2010;Albanesi et al, 2013;Calner et al, 2014). Recently, Lehnert et al (2014) named several positive and negative ␦ 13 C shifts detected in Lower and Middle Ordovician strata, such as Cambrian-Ordovician Transition (COTICE), Top Skullrockian (TSICE), Late Stairsian (LSICE), Late Tremadocian Negative (LTNICE), Basal Floian (BFICE), Basal Dapingian Negative (BDNICE), and Lower Darriwilian Negative (LDNICE) isotope carbon excursions.…”
