Strontium concentration, radiogenic (Sr/Sr) and stable (δSr) strontium isotope systematics in a controlled feeding study
Transhumance and palaeodiet are two central themes in archaeology and using chemical analysis of bones and teeth to reconstruct trends and patterns in diet and mobility has become a cornerstone of bioarchaeology. This study has investigated strontium concentration ([Sr]), radiogenic (Sr/Sr) and stable strontium (δSr) isotope systematics in a controlled feeding experiment on domestic pigs design...
متن کاملMg, Sr and Sr isotope geochemistry of a Belgian Holocene speleothem: implications for paleoclimate reconstructions
87 86 Ž In this study, variations in MgrCa, SrrCa and Srr Sr ratios in a Holocene Belgian speleothem cave secondary . carbonate deposit are interpreted in terms of changes in water residence time and changes in weathering processes, possibly Ž . induced by changes in West European climate. A stalagmite from the Pere Noel cave Belgium was dated with the TIMS ` ̈ UrTh method and was deposited bet...
متن کاملResolving archaeological populations with Sr - isotope mixing models
Strontium isotope analysis of tooth enamel is a useful provenancing technique to investigate the childhood origins and residential mobility of ancient people. However, where different geographical target regions have similar biosphere Sr/Sr it is often difficult to resolve the Sr/Sr ranges of two different groups of people and establish what constitutes the local range at each site. Here a mult...
متن کاملGlobal Climate Change in Marine Stable Isotope Records
Marine stable isotope records provide the basis for much of our understanding of past climates. During the past four decades of research, the exploitation of climatic information contained in marine stable isotopes led to the generation of a global network of marine stable isotope records. In particular, oxygen isotope records have been used to estimate past water temperatures, ice sheet sizes,...
متن کاملCenozoic pelagic Sr/Ca records: Exploring a link to paleoproductivity
[1] Recent studies have revealed that Sr/Ca ratios of coccolithophores may be affected by productivity. Here we compile published Sr/Ca data from bulk carbonate, fine fraction sediment, and planktonic foraminiferal Sr/Ca records that span the past 60 Myr and attempt to place these records into a paleoceanographic framework. We account for changes in seawater Sr/Ca ratios using the curve of Lear...
