Strontium isotopic evidence for prehistoric transport

Through a novel application of strontium (Sr) isotopic analysis, we evaluate geological sources for prehistoric ceramics in the eastern Grand Canyon region of northern Arizona, focusing on two gray-ware traditions in the Upper Basin of the Coconino Plateau. Building on a conceptual framework for the general potential of Sr isotopes in the analysis of geological materials, we suggest that the ...

2004-3-1  We conclude that the transport of Sr differs from the transport of such heavy metals, as Cd, Pb, and Ni, and is similar in many aspects to the distribution of calcium, another alkaline earth metal, probably due to similar physical and chemical properties of their ions.

2012-9-15  Together with calcium isotope and Sr/Ca data from the two investigated species (G. ruber, G. sacculifer) the strontium isotope data point to calcification in a system where only a relatively small percentage of the calcium transported to the site of calcification is used for the formation of calcite.

Application of the trace element and isotope

2013-11-14  The special utility of strontium, compared with other elemental and isotopic systems, lies in (1) substantial vari- ations in its concentration and isotopic composi- tion in sedimentary rocks and waters, which can provide important clues to such parameters as mineralogy, fluid salinity, fluid source and extent of fluid-rock interaction, and (2) the linked trace element partitioning and isotopic mixing

Transport of stable isotopes: I: Development of a

1988-4-1  Determination of the transport mechanism requires data on the spatial distribution of the reaction progress of exchange reactions between minerals and fluids involving at least two stable isotope systems such as 13 C-12 C and 18 O-16 O, for example. It is concluded that a combination of field and laboratory measurements of two or more stable isotope systems can be used to place constraints not only on the mechanism of transport

Strontium isotope analysis on cremated human

2018-8-2  Two isotopes of strontium, 86 Sr and 87 Sr, are widely used in mobility studies of humans and fauna. Strontium-87 is the product of the radioactive decay of rubidium-87 (87 Rb), so strontium...

Strontium isotope studies of atmospheric inputs to ...

Stable isotopes of strontium provide a unique quantification of ecosystem processes because organisms do not differentiate between them. For landscapes with contrasting geologies, these isotopes can identify atmospheric source material from local weathered material. This study quantified the input of strontium, distribution within the ecosystem, canopy capture versus leaf leachate, canopy loss ...

Transport of stable isotopes: I: Development of a

Equations are developed describing migration of stable isotopes via a fluid phase infiltrating porous media. The formalism of continuum fluid mechanics is used to deal with the problem of microscopic inhomogeneity. Provision is made explicitly for local equilibrium exchange of isotopes between minerals and fluids as well as for kinetic control of isotopic exchange.

[PDF] The chemical and strontium isotope

Atmospheric aerosols have been collected at four sites around Japan during 2000. From systematically monitoring the major (Na, Mg, Al, K, Ca, and Fe) and trace (Rb and Sr) elements, along with the Sr isotope composition, we have tried to estimate the contribution of long-range-transported Asian dust (“Kosa”) to the atmospheric aerosols. The results are summarized as follows: (1) The ...
