      abstract     = {Carbon isotope (δ13Corg) analyses of non-marine clastic
                      rocks and neritic carbonates and black shales spanning the
                      Silurian/Devonian transition are compared from two richly
                      fossiliferous sequences in Qujing of East Yunnan and Zoige
                      of Sichuan, South China. The two sections, Xishancun and
                      Putonggou sections in South China, reveal positive δ13Corg
                      shifts happening in the Upper Pridoli and Lower Devonian and
                      reaching peak values as heavy as $–25.2\%‰$ (Xishancun)
                      and $–19.9\%‰$ (Putonggou) in the lowermost Lochkovian
                      following the first occurrence of the thelodont Parathelodus
                      and the conodont Icriodus woschmidti woschmidti (only in
                      Putonggou Section and together with Protathyris-Lanceomyonia
                      brachiopod fauna). These results replicate a globally known
                      positive shift in δ13Corg from the uppermost Silurian to
                      the lowermost Devonian. The δ13Corg variations across the
                      Silurian/Devonian Boundary (SDB) at the two sections in
                      South China exhibit a shift in carbon isotopic composition
                      similar to the detailed SDB curves from the borehole Klonk-1
                      drilled at top of the Klonk Global Standard
                      Stratotype-Section and Point (GSSP) in the Prague Basin,
                      Czech Republic. In addition, four microvertebrate
                      assemblages, including the Liaojiaoshan, Xishancun,
                      Yanglugou and Xiaputonggou assemblages, are recognized from
                      the Silurian/Devonian transition exposed in the Xishancun
                      and Putonggou sections, respectively. The results from both
                      carbon isotope stratigraphy and microvertebrate assemblage
                      sequences suggest that the SDB in South China is located at
                      the base of the Xishancun Formation (between sample QX-20
                      and sample QX-21) in the Xishancun Section and the lower
                      part of the Xiaputonggou Formation (between sample ZP-09 and
                      sample ZP-10) in the Putonggou Section. The isotopic trend
                      for organic carbon together with the changes of
                      microvertebrate remains across the SDB can offer an approach
                      to a potential correlation of the SDB from different
                      sedimentary facies, which help to correlate the marine with
                      non-marine deposits.},
