Abstract:The researches of continental weathering, paleo- marine environment, and organic matter enrichment during Edicaran (Sinian)—Cambrian (E—C) transition stage in the Yangtze area, were organized and summarized in the present study. The results show that, during this stage, the Yangtze area suffered a strong chemical weathering, where includes carbonate platform facies and deep basin facies. The Early Cambrian Niutitang black shale lies with an unconformity upon the Edicaran Dengying dolomite in carbonate platform region, and this unconformity closely connected with the “Great Unconformity” during E—C transition stage around the word. However, in deep basin region, the Niutitang black shale conformably overlies on the Edicaran siliceous rock, and the complete E—C sedimentary strata has preserved weathering record of platform region. The existing geochemical evidences of continental weathering focus on 87Sr/86Sr、δ13C、CIA, and εNd(t), and these geochemical data are limited to a few geological sections. Thus, more new geochemical factors are urgently needed to indicate the influence and evolution of the continental weathering during E—C transition stage. Finally, we suggest that an accurate understanding of coupling relationship between continental weathering and marine environment is significant for recognizing the evolution of life, and the enrichment of organic matter.
