Local paleoenvironmental controls on the carbon-isotope record defining the Bitter Springs Anomaly
Large magnitude (>10‰) carbon-isotope (δ13C) excursions recorded in carbonate-bearing sediments are increasingly used to monitor environmental change and constrain the chronology of the critical interval in the Neoproterozoic stratigraphic record that is timed with the first appearance and radiation of metazoan life. The ~10‰ Bitter Springs Anomaly preserved in Tonian-aged (1000–720 Ma) carbonate rocks in the Amadeus Basin of central Australia has been offered as one of the best...[Show more]
