| Summary: | From measurements of 187Os/186Os ratios in marine Mn nodules and comparison with the 143Nd/144Nd ratios of the same nodules, the Os isotopic composition and the Os and Re concentrations of the weatherable portion of the continental crust are estimated, together with the proportions of the 'ultramafic' and 'granitic' rocks that constitute this crustal mass.
