Scientific paper

The present study reports Re and Os concentrations and Os isotropic composition for ultramafic samples from ophiolites. Present-day Os-187/Os-186 for the upper mantle is found to be constrained, for the time being, around 1.05-1.06. The mantle evolution curve for osmium isotopes through time, when associated with recent Os isotopic determinations from the literature for Archaean samples, shows a 'chondritic' Re-187/Os-196 ratio of 3.33 and a linear closed-system evolution.
