文摘

Continental carbonates are among the most 88Sr-depleted Sr reservoirs on earth. Δ88/86Sr between continental carbonates and precipitating waters is −0.218±0.014‰−0.218±0.014‰. Ca-carbonate precipitation is a significant mechanism in the continental Sr cycle. Average δ88/86Sr of marine carbonate rocks maybe higher than current literature value.
