^(238)U/^(235)U in marine carbonates as a tracer of Precambrian paleoredox conditions
Abstract
The timing and magnitude of the oxygenation of Earth's ocean is still a matter of intense debate. Previous work suggested that the uranium isotope variations recorded in ancient marine sediments, such as shales and carbonates, could provide valuable insights into paleoredox conditions [e.g., 1-11]. In this work, we study U concentration and isotopic composition of a large number of Precambrian carbonates to place constraints on long-term variations in oceanic redox conditions.
