摘要Here, we document a detailed characterisation of two zircon gemstones, GZ7 and GZ8. Both stones had the same mass at 19.2 carats (3.84 g) each; both came from placer deposits in the Ratnapura district, Sri Lanka. The U-Pb data are in both cases concordant within the uncertainties of decay constants and yield weighted mean Pb-206/U-238 ages (95% confidence uncertainty) of 530.26 Ma +/- 0.05 Ma (GZ7) and 543.92 Ma +/- 0.06 Ma (GZ8). Neither GZ7 nor GZ8 have been subjected to any gem enhancement by heating. Structure-related parameters correspond well with the calculated alpha doses of 1.48 x 10(18) g(-1) (GZ7) and 2.53 x 10(18) g(-1) (GZ8), respectively, and the (U-Th)/He ages of 438 Ma +/- 3 Ma (2s) for GZ7 and 426 Ma +/- 9 Ma (2s) for GZ8 are typical of unheated zircon from Sri Lanka. The mean U mass fractions are 680 mu g g(-1) (GZ7) and 1305 mu g g(-1) (GZ8). The two zircon samples are proposed as reference materials for SIMS (secondary ion mass spectrometry) U-Pb geochronology. In addition, GZ7 (Ti mass fractions 25.08 mu g g(-1) +/- 0.18 mu g g(-1); 95% confidence uncertainty) may prove useful as reference material for Ti-in-zircon temperature estimates.
