Resolving crystallisation ages of Archean mafic-ultramafic rocks using the Re-Os isotope system
Rhenium-Osmium (Re-Os) isotope and elemental data are presented for mafic-ultramafic rocks from the central region of the Lewisian Archean terrain in northwest Scotland. These results give a best estimate for the time of emplacement of the mafic-ultramafic bodies of 2686.7 ± 14.7 Myr (2σ). The initi...
