Lower Triassic δ13C isotope curve from shallow-marine carbonates in Japan, Panthalassa realm : Confirmation of the Tethys δ13C curve
δ13C data from Tethyan sections provide evidence of profound changes in the carbon cycle during the Lower Triassic. Sections from the Panthalassa realm were investigated to establish whether these variations are also present there. In the Jurassic accretionary wedges in Japan, exotic blocks having a Panthalassan affinity, have been incorporated. The majority of the blocks are pelagic cherts but ra
