New publications: U isotope modeling and a review of the proxy in carbonate records

Today's special issue in Geochimica et Cosmochimica Acta has two publications to highlight. The first is a reactive transport model of uranium isotopes in marine reducing environments that was started as a Ph.D. project and completed as part of my postdoc: Uranium reduction and isotopic fractionation in reducing sediments: Insights from reactive transport modeling. The model allows us to explore the important depositional factors that ultimately control seawater uranium isotopes. Check out the figure below and download the PDF here. 

Feifei Zhang and colleagues also have published a review on the uranium isotope proxy in carbonates, titled Uranium isotopes in marine carbonates as a global ocean paleoredox proxy: A critical review. You can download the PDF here.
