- Vesuvianites from the Early Proterozoic Björntjärn tungsten skarn deposit in northern Sweden were dated with the U-Pb and Pb-Pb methods. Low206Pb/204Pb values make the U-Pb dating of vesuvianite rather sensitive to the common lead correction. However, the combination of Pb-Pb and U-Pb data on the same material permits the deduction of precise ages on Proterozoic vesuvianites. Vesuvianite can be used to date the formation of skarn mineralizations and possibly also the metamorphism and metasomatism of argillaceous limestones
