dc.description.abstract	The viability of oxygen isotope analysis of tooth enamel by UV laser ablation and fluorination has been demonstrated by comparison with the Ag3PO4 extraction method. In-situ analyses by UV laser fluorination using both isotope ratio mass spectrometry and isotope ratio monitoring gas chromatography mass spectrometry (irm-GCMS) microanalysis are comparable to those of the Ag3PO4 method with a mean precision of +/-0.4%% (1σ) for samples with δ18O values ranging from 10.8 to 20.8%%. UV laser ablation provides spatial resolution of 100 μm or less with no laser reaction rim. These data show that irm-GCMS offers a combination of spatial and analytical precision for in-situ sampling of biogenic apatites previously unobtainable by other means.
