Summary:To constrain the causes of 87Sr/86Sr variations, the 87Sr/86Sr ratios in carefully cleaned, unrecrystallized foraminifera from DSDP sites 21 and 357 were measured. The data presented here were qualitatively modelled, taking account of recent understanding of the Sr geochemical cycle. They suggest that the major control of the 87Sr/86Sr variations through the Cainozoic has been changes in the isotope composition of Sr derived from the weathering of silicate rocks. [C.N.]
