Biostratigraphy and Glaciations in the Neoproterozoic: Updates from Re-Os geochronology
Sedimentary strata from the Neoproterozoic Era (1000-541 Ma) host evidence for widespread glaciations, major fluctuations in geochemical proxy records, and numerous biological innovations associated with the diversification of eukaryotes that culminated with the emergence of Metazoans. Understanding the drivers and rates of change through this critical transition has been limited by the lack of a robust chronology. Here I will present multiple new Re-Os and U-Pb geochronology data from Neoproterozoic strata in an attempt to refine global correlation schemes and further constrain this critical interval of Earth history.
