| Abstract: | Based on the outcrop sequence stratigraphic analysis of the typical Upper Sinian carbonate rocks from Tianwan ore area,Shimian,Sichuan.4 thirdorder sequences are examined in detail with particular attention to the key surfaces.The characteristics of sequences are described in present paper.Finally,a discussion is made to the sea level change and the relation between the depositional system tracts of sequence stratigraphy and the noble metal deposits during the Late Sinian in Tianwan,Shimian. |
