英文摘要The precision and accuracy of Ar-40/Ar-39 dates are ultimately linked to co-irradiated reference materials of known age. Here we provide new data from the SK01 sanidine, which was analysed in three different laboratories to evaluate it as a Ar-40/Ar-39 reference material. Aliquots of 5 mg, incrementally heated in two laboratories, yielded indistinguishable results with a weighted mean age of 27.58 +/- 0.06 Ma (95% confidence level). Single-crystal step heating and single-crystal total fusion analyses of SK01 sanidine were undertaken in the third laboratory to further test the intracrystalline homogeneity. For the seven step-heating analyses, six crystals yielded nearly concordant age spectra with Ar-40/Ar-39 ages ranging from 26.853 +/- 0.094 Ma to 26.963 +/- 0.067 Ma, whereas one crystal gave an older age of 27.774 +/- 0.071 Ma with a slightly discordant age spectrum. Twenty-three single-crystal total fusion analyses yielded Ar-40/Ar-39 ages ranging from 27.070 +/- 0.108 Ma to 27.736 +/- 0.062 Ma with a dispersion of similar to 3.8%. The older ages from single-crystal total fusion dates are interpreted to reflect an inherited or excess argon component in some crystals. This is an initial characterisation of the SK01 sanidine, and additional work needs to be conducted to further evaluate the age dispersion so that it can be utilised as a Ar-40/Ar-39 reference material.
