Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic ...

Scientists from Northwestern have published new findings on the factors that triggered the oceanic anoxic event (OAE) 1a in the Early Cretaceous Period about120 million years ago. The unprecedented ...

A team of researchers led by UC Santa Cruz recently released a sophisticated new map that reveals, for the first time, the unique “geologic fingerprints” for most of the African continent. The map ...

Your teeth contain traces of strontium isotopes that can reveal where you lived while they were forming. Hosted by: Michael ...

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years.

APPLICATION of high resolution to accelerated anode rays has now provided improved mass-spectra of these two elements. Strontium shows a third isotope 87 in addition to those already observed. Results ...

Misha lived her whole life in zoos, but this elephant's teeth are now helping scientists reconstruct wildlife migrations. Geologists show how strontium isotopes found in teeth or tusks reveal where ...

A new study supports the hypothesis that the Ontong Java Plateau large igneous province eruptions led to oceanic anoxic event 1a, 127 to 100 million years ago. Around 120 million years ago, the earth ...

Marine barite extracted from deep-sea sediment cores, seen here in a scanning electron microscope image, provides a record of variations in ocean chemistry over geologic time. (Image by Adina Paytan) ...
