Assessing the reliability of modern marine stromatolites as archives for the uranium isotope paleoredox proxy

Geochimica et Cosmochimica Acta, 2023
Uranium isotopes (238U/235U) are commonly utilised in marine carbonates to reconstruct the redox evolution of ancient oceans and the atmosphere. However, questions remain concerning U isotope fractionation during carbonate precipitation and/or early sedimentary diagenesis. Moreover, the stromatolitic nature of many Precambrian limestones and dolostones

Reconstructing Paleoredox Conditions through a Multitracer Approach: The Key to the Past Is the Present

Elements, 2009
Knowledge about paleoredox conditions is essential for reconstructing how the oxygenation of the Earth's surface environment has changed through time and affected the evolution of life on our planet. Some metal stable isotope systems, such as Mo isotopes, record the extent of ocean oxygenation directly.

Uranium isotope fractionation in Saanich Inlet: A modern analog study of a paleoredox tracer

Geochimica et Cosmochimica Acta, 2015
Abstract Uranium isotope fractionation was studied in the sediment and water of Saanich Inlet, a seasonally anoxic fjord on the east coast of Vancouver Island. The concentration of dissolved U is the same above and below the redoxcline at ∼120 m depth, with an average δ238U value of −0.45 ± 0.06‰ (2 s.e.), which is indistinguishable from seawater ...
