9316238 Knoll PI and collaborators (including Guy Narbonne of Queens University in Canada) will collect and analyze geochemically samples of Neoproterozoic (c. 1000-545 Ma) rocks in northwestern Canada. These analyses will refine and extend an increasing body of data showing that significant temporal variations in isotopic composition of seawater characterize this time period. These variations in carbon and strontium isotopes are important tools for global correlations, and help to elucidate geologic and biological events from this time. ***

9316238 Knoll Pi和他的合作者(包括加拿大皇后大学的Guy Narbonne)将收集和分析加拿大西北部新元古代(约1000-545 Ma)岩石的地球化学样本。这些分析将完善和扩展越来越多的数据，表明海水同位素组成的显着时间变化是这一时期的特征。碳和锶同位素的这些变化是全球对比的重要工具，并有助于阐明自那时以来的地质和生物事件。***
