    Re-Os Isotope and HSE Abundance Systematics of the 2.9 Ga Komatiites and Basalts from the Sumozero-Kenozero Greenstone Belt, SE Fennoscandian Shield: Implications for the Mixing Rates of the Mantle

    Rhenium-Os isotope and highly siderophile element (HSE, including Re, Os, Ir, Ru, Pt, and Pd) abundance systematics of Archean komatiites can be used to estimate the stirring rates of the mantle for the HSE an...

    Mantle data imply a decline of oxidizable volcanic gases could have triggered the Great Oxidation

    Aerobic lifeforms, including humans, thrive because of abundant atmospheric O2, but for much of Earth history O2 levels were low. Even after evidence for oxygenic photosynthesis appeared, the atmosphere remained ...

    An oceanic subduction origin for Archaean granitoids revealed by silicon isotopes

    Modern oceanic crust is constantly produced at oceanic ridges and recycled back into the mantle at subduction zones via plate tectonics. An outstanding question in geology is whether the Earth started in a non...

    Tungsten isotopic evidence for disproportional late accretion to the Earth and Moon

    Examination of three lunar samples reveals that the Moon’s mantle has an excess of the tungsten isotope 182W of about 20 parts per million relative to the present-day Earth’s mantle; this suggests that the two bo...
