Rhenium-osmium isotope and elemental behaviour during subduction of oceanic crust and the implications for mantle recycling
- Abstract:
-
This study presents major-, trace-element, and rhenium-osmium (Re-Os) isotope and elemental data for basalts and gabbros from the Zermatt-Saas ophiolite, metamorphosed to eclogite-facies conditions during the Alpine orogeny. Igneous crystallisation of the gabbros occurred at 163.5 ± 1.8 Ma and both gabbro and basalt were subject to 'peak' pressure-temperature (P-T) conditions of > 2.0 GPa and ~ 600 °C at about 40.6 ± 2.6 Ma. Despite such extreme P-T conditions, Re-Os isotope and abundance ...
