DESCRIPTION:Strontium isotope analysis (87Sr/86Sr) are now commonly used i
 n archaeology to track mobility and migration of past human and animal pop
 ulations\, as well as gaining insights into landscape use\, exchanges\, an
 d trade. However\, diagenesis is an important factor to consider when sele
 cting adequate samples for analyses. Currently\, tooth enamel and calcined
  bone/dentine are considered as reliable proxies for such analyses\, while
  unburnt bone/dentine\, wood\, charred crops\, etc.\, are affected by post
 -burial strontium exchanges with the soil in which they are buried. The in
 creasing use of strontium isotope analysis on human and animal remains is 
 creating a large amount of data that is not always straightforward to inte
 rpret. Adequate baselines (often called biologically available strontium b
 aselines) are needed to assess if an individual was “local” or not\, w
 hich are not always available\, or not detailed enough. This presentation 
 will discuss the current challenges\, limitations\, and perspectives for t
 he use of strontium isotope analysis in bioarchaeology and the creation of
  biologically available strontium baselines. \n\n
