Strontium isotopes in deep-sea sediments.
Recent deep-sea sediments, leached of carbonate, have Sr(87) Sr(86) ratios ranging from 0.7044 to 0.7394. Strontium in the detrital sediment has not equilibrated isotopically with seawater strontium. Amounts of strontium-bearing authigenic material in the clay-mineral assemblage are not great enough to mask strontium-isotope ratios inherited from source areas.
