The scale and origin of the osmium isotope variations in mid-ocean ridge basalts
- Abstract:
-
The decay of 187Re to 187Os provides a unique tracer of recycled lithosphere in the Earth's upper mantle, and the radiogenic Os isotope compositions of many mid-ocean ridge basalts (MORB) have been taken to indicate the presence of recycled oceanic crust in the mantle source. However, others have attributed the data to contamination by seawater or an age effect (due to 187Re decay following igneous crystallisation). This study presents new Re-Os, U-Th-Ra and B isotope data for normal-MORB (N-...
