Sample preservation was evaluated from scanning electron microscopy studies, measured strontium-calcium ratios, and pore water strontium isotope ratios. The evolution of the strontium isotopic ratio in seawater offers a means to evaluate long-term changes in the global strontium isotope mass balance. Results show that the marine strontium isotope composition can be used for correlating and dating well-preserved authigenic marine sediments throughout much of the Cenozoic to a precision of +/- 1 million years. The strontium-87 to strontium-86 ratio in seawater increased sharply across the Cretaceous/Tertiary boundary, but this feature is not readily explained as strontium input from a bolide impact on land.","descriptionType":"Abstract"},{"description":"Supplement to: Hess, Jennifer; Bender, Michael L; Schilling, Jean-Guy (1986): Evolution of the ratio of strontium-87 to strontium-86 in seawater from Cretaceous to present.
