| Abstract: | Methods of outcrop sequence stratigraphy are applied to detail study of the Sinian System in the Qipan Valley, Wenchuan County and the Yangmudong Stream, Guangyuan City. The Upper Sinian Series may be divided into 1 second-order sequence, 4 third-order sequences and 3 isochronous surfaces on the basis of rock association, basic sequence and sedimentary facies etc. The isochronous stratigraphic framework of the Upper Sinian Series is set up and the curve of relative change of sea level in the Late Sinian is drawn. |
