"There and back again: Strontium isotopes provide insight into landscape use and migration of mammoths, mastodons, caribou, and other adventurers": A joint talk by Josh Miller and Abby Kelly, University of Cincinnati.
Our interdisciplinary research applies new advances in strontium isotope tracing protocols enabling us to go a step further in unravelling the life of bog people. Our study reveals long distance travel of the Haraldskær Woman shortly before her death, leading to new speculations on .
A refined strontium isotope curve through this time period may offer insight into the environmental conditions of the early Cambrian. New age models and detailed mapping in the Zavkhan terrane in westcentral Mongolia provide the context necessary for robust geochemical analysis.
Strontium salts are used in flares and fireworks for a crimson color. Strontium chloride is used in toothpaste for sensitive teeth. Strontium oxide is used to improve the quality of pottery glazes. The isotope 90 Sr is one of the best longlived, highenergy beta emitters known. It is used in cancer therapy.
Strontium is a mineral found in seawater and soil. In your diet, you get it mainly from seafood, but you can also get small amounts of it in whole milk, wheat bran, meat, poultry, and root vegetables. Strontium is similar to calcium. It seems to play a role in how your body makes new .
Elemental ratios of calcium (Ca), strontium (Sr) and barium (Ba) in plant tissue have been used to help identify sources of Ca in trees. However, recent work has clearly shown that ratios of Ca:Sr or...
Retrospective determination of natal habitats for an estuarine fish with otolith strontium isotope ratios James A. HobbsA,C, QingzhuYinB, Jessica BurtonA and William A. BennettA ABodega Marine Laboratory, University of California, Davis, John Muir Institute of the Environment, University of California, Davis, One Shields Avenue, Davis, CA ...
Aug 31, 2018· Lead researcher Huan Cui analyzing isotopes in the wet lab at the University of Wisconsin–Madison. Oxygen, carbon, strontium and sulfur isotopes during the Neoproterozoic reveal a stepwise pattern of atmospheric oxygen, crucial to the evolution of complex life.
Aug 02, 2018· New light shed on the people who built Stonehenge. Instead, they found the highest strontium isotope ratios in the remains were consistent with living in western Britain, a region that includes west Wales—the known source of Stonehenge's bluestones. Although strontium isotope ratios alone cannot distinguish between places with similar values,...
you learned about strontium isotope analyses of the mineral in teeth and bone as a method to reconstruct aspects of an individual's migratory history. With this method, it is in some cases possible

Jan 10, 2012· Its manmade isotope strontium (atomic weight 90) is radioactive. Like calcium, strontium is a Group 2 element in the periodic table and is placed just beneath calcium. In other words, it's chemical properties and behaviour are very similar. (1) Now let us look at the prescribed variants – strontium ranelate and strontium citrate.
Jun 24, 2008· Strontium isotope constraints on fluid flow in the sheeted dike complex of fast spreading crust: Pervasive fluid flow at Pito Deep. A. K. Barker. ... [36] The misfit between the models and data provides insight into whether Sr‐isotope exchange occurs solely during recharge as .
Strontium isotopes Strontium isotope stratigraphy relies on measurement of 87 Sr/ 86 Sr in marine biogenic carbonate or phosphate. Precipitation of these minerals involves incorporation of strontium from seawater, which will have an 87 Sr/ 86 Sr identical to that of oceanic values, which is of the same value globally at any point in time.
Strontium Isotope Analysis. The isoscape generated in this study provides the most accurate 87 Sr/ 86 Sr predictions in bioavailable strontium for Western Europe (R 2 = and RMSE = ) to date, as well as a conservative estimate of spatial uncertainty by applying quantile regression forest.
Stable and radioactive isotope studies provide insight into the geochemical evolution of rock units. Radioiodine is a radioactive isotope of iodine that is taken up and concentrated by the thyroid gland. Each microsphere is coated with a radioactive isotope which emits beta radiation.
Mar 03, 2019· Strontium isotopes of marine archives provide a significant means for tracing physical and chemical processes operating over geologic time. Modern articulated brachiopods and halite samples were collected from all depths of the world's main water bodies.
