“…Investigations on glacio-eustasy and carbonate δ 13 C across the MPB came mostly from Euramerica, and the studied MPB successions were all deposited in epeiric carbonate platforms that were punctuated by either development of palaeokarsts, palaeosols, and incised valleys, or input of siliciclastics (Barnett & Wright, 2008;Bishop et al, 2009;Blake & Beuthin, 2008;Brand & Bruckschen, 2002;Cecil & Englund, 1989;Davydov & Puchkov, 2009;Dvorjanin et al, 1996;Kabanov, Alekseev, Gibshman, Gabdullin, & Bershov, 2016). Furthermore, the carbonate δ 13 C recorded in shallow epeiric carbonate platforms was either readily altered by meteoric diagenesis given the repeated subaerial exposures (e.g., Algeo, Wilkinson, & Lohmann, 1992;Bruckschen et al, 1999;Saltzman, 2003) or decoupled from the ocean water values due to local processes on platforms (e.g., Brand, Tazawa, Sano, Azmy, & Lee, 2009;Immenhauser, Della Porta, Kenter, & Bahamonde, 2003;Panchuk, Holmden, & Kump, 2005;Patterson & Walter, 1994).…”
