| Sintesi≠ | Strontium isotope provenance analysis uses the ratios of strontium-87 to strontium-86 in human skeletal remains to determine geographic origin and track human mobility and migration. Developed by Jonathan Ericson in the 1980s, this method exploits the fact that strontium isotope ratios in the environment vary geographically based on underlying geology. When individuals consume food and water from a specific region, they incorporate that region's characteristic strontium isotope signature into their bones and teeth, creating a geochemical fingerprint of their residence. | Instrumental neutron activation analysis (INAA) measures trace element concentrations in archaeological artifacts by bombarding samples with neutrons and analyzing the resulting gamma-ray emissions. Developed as a systematic archaeological method by Michael Glascock and colleagues, INAA provides chemical fingerprints of ceramics, obsidian, and other materials that reveal sourcing and provenance. The method is non-destructive, highly sensitive, and capable of detecting 30+ elements simultaneously. |
