Like the recently published data for Deep Sea Drilling Preject (DSDP) carbonates, /sup 87/Sr//sup 846/Sr at Enewetak increases menotonically but net smoothly from the early Miccene to the Fleistocene. The data show intervals of little or ne change in /sup 7/Sr//sup 36/Sr, punctuated by sharp transitions tea lower values toward greate- cere depthe.
