中国南方扬子地台埃迪卡拉-寒武系过渡带两个斜坡-盆地剖面的有机碳同位素数据记录了C-13三角洲的长期变化。数据补充高度可比的有机碳同位素配置文件从时间相当的浅水架和斜坡设置。没有环境确定的碳同位素梯度在整个扬子地台是可辨别的，这表明海侵缺氧事件提供了一个同位素均匀的碳源的初级生产力，起源于较深的缺氧和/或硫化物盆地。(C)2011 Elsevier B. V.保留所有权利。
Organic carbon isotope data from two slope to basinal sections across the Ediacaran-Cambrian transition on the Yangtze Platform, South China record secular variations in delta C-13. Data supplement highly comparable organic carbon isotope profiles from time equivalent shallow shelf and slope settings. No environmentally determined carbon isotope gradient across the Yangtze Platform is discernible, suggesting that a transgressive anoxic event provided an isotopically homogenous carbon source for primary productivity that originated from the deeper part of an anoxic and/or sulfidic basin.
