回复：S.- Y. Jianget al.Nature459，10.1038/nature 08048（2009）Jianget al.提出了中国牛蹄塘组最低黑色页岩序列中灰层的SHRIMP锆石U-Pb年龄为532.3 ± 0.7百万年（Myr），并声称，我们最近的论文中提出的数据并不能坚定地支持前寒武纪生物和环境变化的观点。寒武纪的转变可以用单一的全球硫化氢（H2S）释放事件来解释。最近的另一项SHRIMP调查似乎支持了他们的新年龄，该调查确实表明中国富含金属的硫化物层并不代表前寒武纪/寒武纪边界，并表明两个盆地（阿曼和华南）的氧化还原历史要复杂得多。
Replying to: S.-Y. Jianget al.Nature459, 10.1038/nature08048 (2009)Jianget al.present a new SHRIMP U–Pb zircon age of 532.3 ± 0.7 million years (Myr) ago for an ash bed in the lowermost black shale sequence of the Niutitang Formation, China, and claim that the data presented in our recent paper do not firmly support the idea that the biological and environmental changes at the Precambrian/Cambrian transition can be explained by a single global hydrogen sulphide (H2S) release event. Their new age seems to be supported by another recent SHRIMP investigation which indeed suggests that the Chinese metal-enriched sulphide layer does not represent the Precambrian/Cambrian boundary and shows that the redox history of both basins (Oman and South China) was much more complex.
