Description
Laser ablation multi collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) allows for fast and targeted 87Sr/86Sr analysis on archaeological material. A method for applying laser ablation on tooth enamel has been developed and allows for analysis spots 200µm square and ~20µm deep. The petrous bone has emerged as an alternative target for Sr analysis in cremated remains, and the differ-ing tissue turnover rates within this bone may allow for isotopic histories within a per-son to be uncovered. The small spot size of laser ablation could allow for multiple measurements on a variety of tissues within the petrous bone structure.This paper will present the use of LA-MC-ICP-MS on cremated petrous bones alongside human teeth from individuals buried at several Portuguese sites. Interest-ing patterns of 87Sr/86Sr variation within bones and within measurements of the same spot emerged. Methodological challenges and data corrections will also be dis-cussed.
