"Re-Os and Mo Isotope Systematics of Black Shales from the Middle Proterozoic Velkerri and Wollogorang Formations, McArthur Basin, Northern Australia" in Geochimica Cosmochimica Acta is now available here. Coauthored with Rob Creaser (at the University of Alberta), Gwyneth Gordon and Ariel Anbar, this paper represents an exciting combination of careful age dating with the Re-Os method and Mo isotopes for constraining the paleoredox of the ancient oceans at this time. Dr. Kendall is currently the only scientist implementing both isotope systems to closely link paleoredox to precise points in Earth history.
