“…In particular, OAE 1a is marked by a complex C isotopic anomaly that has been recognized in the Tethys, North Atlantic, and Pacifi c Oceans (Weissert, 1989;Weissert and Lini, 1991;Grötsch, 1993;Bralower et al, 1994Bralower et al, , 1999Jenkyns, 1995;Vahrenkamp, 1996Vahrenkamp, , 2010Ferreri et al, 1997;Menegatti et al, 1998;Erba et al, 1999;Jenkyns and Wilson, 1999;Luciani et al, 2001;Ando et al, 2002;Bellanca et al, 2002;Price, 2003;Immenhauser et al, 2005;Millán et al, 2009;Hu et al, 2012a;Huck et al, 2012;Bottini et al, 2014), and in terrestrial sequences (Gröcke et al, 1999;Hesselbo et al, 2000;Jahren et al, 2001;Heimhofer et al, 2003). An initial negative spike documented in marine and terrestrial records suggests a large input of isotopically light carbon into the ocean-atmosphere system, perhaps due to intensifi ed volcanogenic CO 2 emissions during the GOJE (Larson, 1991a;Weissert and Lini, 1991;Bralower et al, 1994;Erba, 1994;Weissert et al, 1998;Menegatti et al, 1998;Larson and Erba, 1999;Price, 2003), methane liberation from gas-hydrate dissociation (Gröcke et al, 1999;Hesselbo et al, 2000;Jahren et al, 2001;Beerling et al, 2002;…”

The mid-Cretaceous was marked by emplacement of large igneous provinces (LIPs) that formed gigantic oceanic plateaus, affecting ecosystems on a global scale, with biota forced to face excess CO 2 resulting in climate and ocean perturbations. Volcanic phases of the Ontong Java Plateau (OJP) and the southern Kerguelen Plateau (SKP) are radiometrically dated and correlate with paleoenvironmental changes, suggesting causal links between LIPs and ecosystem responses. Aptian biocalcifi cation crises and recoveries are broadly coeval with C, Pb, and Os isotopic anomalies, trace metal infl uxes, global anoxia, and climate changes. Early Aptian greenhouse or supergreenhouse conditions were followed by prolonged cooling during the late Aptian, when OJP and SKP developed, respectively. Massive volcanism occurring at equatorial versus high paleolatitudes and submarine versus subaerial settings triggered very different climate responses but similar disruptions in the marine carbonate system. Excess CO 2 arguably induced episodic ocean acidifi cation that was detrimental to

“…OAEs are defined as short-lived (<1 My) episodes of enhanced deposition of organic carbon in a wide range of marine environments (Schlanger and Jenkyns, 1976) and are associated with prominent carbon isotope excursions in marine and terrestrial sequences (Jenkyns, 1980(Jenkyns, , 2010Arthur et al, 1988;Gröcke et al, 1999;Jahren et al, 2001;Ando et al, 2002;Jarvis et al, 2006). Generation of OAEs has been attributed to a rapid influx of volcanogenic and/or methanogenic CO 2 sources leading to abrupt temperature rise and an accelerated hydrological cycle, increased continental weathering and nutrient discharge to oceans and lakes, intensified upwelling, and an increase in organic productivity.…”

“…The last occurrence of C. septemporatus was identified in the middle to upper Shirikishimanaigawa Formation in all areas. The basal part of the Yezo Group was correlated with the lower Aptian, based on the integrated stratigraphy of planktonic foraminifera, radiolaria and carbon isotope ratios (Ando et al 2002(Ando et al , 2003Takashima et al 2004).…”

-The Sorachi Group, composed of Upper Jurassic ophiolite and Lower Cretaceous island-arc volcano-sedimentary cover, provides a record of Late Jurassic-Early Cretaceous sedimentation and volcanism in an island-arc setting off the eastern margin of the Asian continent. Stratigraphic changes in the nature and volume of the Sorachi Group volcanic and volcaniclastic rocks reveal four tectonic stages. These stages resulted from changes in the subduction direction of the Pacific oceanic plate. Stage I in the Late Jurassic was characterized by extensive submarine eruptions of tholeiitic basalt from the back-arc basin. Slab roll-back caused rifting and sea-floor spreading in the supra-subduction zone along the active Asian continental margin. Stage II corresponded to the Berriasian and featured localized trachyandesitic volcanism that formed volcanic islands with typical island-arc chemical compositions. At the beginning of this stage, movement of the Pacific oceanic plate shifted from northeastward to northwestward. During Stage III, in the Valanginian, submarine basaltic volcanism was followed by subsidence. The Pacific oceanic plate motion turned clockwise, and the plate boundary between the Asian continent and the Pacific oceanic plate changed from convergent to transform. During Stage IV in the Hauterivian-Barremian, in situ volcanism ceased in the Sorachi-Yezo basin, and the volcanic front migrated west of the Sorachi-Yezo basin.
