PANGAEA, https://doi.org/10.1594/PANGAEA.772140, Supplement to: Capo, RC; DePaolo, DJ (1990): Seawater Strontium isotopic variations from 2.5 million years ago to the present. Science, 249(4964), 51-55, https://doi.org/10.1126/science.249.4964.51 Abstract: Measurements of marine carbonate samples indicate that during the past 2.5 million years the 87Sr/86Sr ratio of seawater has increased by 14 * 10**-5. The high average rate of increase of 87Sr/86Sr indicates that continental weathering rates were exceptionally high. Nonuniformity in the rate of increase suggests that weathering rates fluctuated by as much as ±30 percent of present-day values. Some of the observed shifts in weathering rates are contemporaneous with climatic changes inferred from records of oxygen isotopes and carbonate preservation in deep sea sediments.
