87Sr/86Sr ratios of planktonic foraminifers and interstitial waters at DSDP Hole 90-593
Listed in PANGAEA
Detailed profiles of the Sr isotopic compositions of fossil planktonic foraminifers and interstitial waters have been measured from DSDP Site 593 to determine the Sr isotopic composition of seawater during the last 40 m.y.
Description
Foraminiferal recrystallization was assessed through scanning electron microscopy (SEM) and Sr/Ca ratios. Foraminifers were shown to be well preserved.
Results document that the seawater 87Sr/86Sr has increased continuously but not uniformly, since the latest Eocene.
