Ariel D. Anbar,Yun Duan,Timothy W. Lyons,Gail Lee Arnold,Brian Kendall,Robert A. Creaser,Alan J. Kaufman,Gwyneth W. Gordon,C. Scott,Jessica Garvin,Roger Buick +10 more
TL;DR: In this article, high-resolution chemostratigraphy reveals an episode of enrichment of the redox-sensitive transition metals molybdenum and rhenium in the late Archean Mount McRae Shale in Western Australia.
Journal ArticleDOI

Felisa Wolfe-Simon,Felisa Wolfe-Simon,Jodi Switzer Blum,Thomas R. Kulp,Gwyneth W. Gordon,Shelley E. Hoeft,Jennifer Pett-Ridge,John F. Stolz,Samuel M. Webb,Peter K. Weber,Paul Davies,Paul Davies,Ariel D. Anbar,Ariel D. Anbar,Ronald S. Oremland +14 more
TL;DR: A bacterium is described, isolated from Mono Lake, California, that is able to substitute arsenic for phosphorus to sustain its growth and exchange of one of the major bio-elements may have profound evolutionary and geochemical importance.
Journal ArticleDOI
Natural fractionation of 238U/235U
TL;DR: In this article, the authors report variations of the 238U/235U isotope ratio in natural samples (basalts, granites, seawater, corals, black shales, suboxic sediments, ferromanganese crusts/nodules and BIFs) of ∼1.3.
Journal ArticleDOI
Devonian rise in atmospheric oxygen correlated to the radiations of terrestrial plants and large predatory fish
Tais W. Dahl,Emma U. Hammarlund,Emma U. Hammarlund,Emma U. Hammarlund,Ariel D. Anbar,David P.G. Bond,Benjamin C. Gill,Gwyneth W. Gordon,Andrew H. Knoll,Arne Thorshøj Nielsen,Niels H. Schovsbo,Donald E. Canfield +11 more
TL;DR: The isotopic composition and concentration of molybdenum in sedimentary rocks are used to couple the redox history of the atmosphere and oceans to major events in animal evolution, suggesting two episodes of global ocean oxygenation and suggesting that early metazoans evolved in a relatively low oxygen environment.
Journal ArticleDOI
Re-Os and Mo isotope systematics of black shales from the Middle Proterozoic Velkerri and Wollogorang Formations, McArthur Basin, northern Australia
TL;DR: In this article, the authors reported new Re-Os and Mo isotope data for the Mesoproterozoic Velkerri Formation (Roper Group) and the PaleoproTERozoic Wollogorang Formation (Tawallah Group), McArthur Basin, northern Australia.
