      abstract     = {Carbon isotope (delta C-13(org)) analyses of neritic
                      carbonates and block shales spanning the Silurian-Devonian
                      transition are compared from two richly fossiliferous
                      sequences in Zoige County (West Qinling Region) of Sichuan
                      Province, China. The two sections. Putonggou and Yanglugou
                      sections in West Qinling, reveal positive delta C-13(org)
                      shifts happening in the upper Pridoli and lower Devonian and
                      reaching peak values as heavy as -19.9 parts per thousand
                      (Putonggou) and -19.7 parts per thousand (Yanglugou) in the
                      lowermost Lochkovian following the first occurrence of the
                      Protathyris-Lanceomyonia brachiopod fauna and the conodont
                      Icriodus woschmidti woschmidti. These results replicate a
                      globally known positive shift in delta C-13(org) from the
                      uppermost Silurian to the lowermost Devonian. The isotopic
                      trend for organic carbon across the Silurian-Devonian
                      Boundary (SDB) offers an approach to a potential correlation
                      of the SDB from different sedimentary facies. The delta
                      C-13(org) variations across the Silurian-Devonian transition
                      at the two sections in West Qinling exhibit a similar shift
                      in their carbon isotopic composition as the detailed SDB
                      curves from the borehole Klonk-1 drilled at top of the Klonk
                      GSSP in the Prague Basin, Czech Republic. This suggests that
                      the SOB in West Qinling is located at the upper part of the
                      Yanglugou Formation (between ZY-07 and ZY-06) in the
                      Yanglugou Section and the lower part of the Xiaputonggou
                      Formation (between ZP-09 and ZP-10) in the Putonggou
                      Section. More data will help to reveal individual causes for
                      the isotopic shift, such as enhanced carbon burial due to
                      anoxic conditions and/or increased productivity, alternating
                      arid and humid periods, or changes in the composition of
                      primary producers.},
