Analytical procedures for V-Pb isotope dilution analyses at the Geological Survey of Canada geochronol­ogy laboratory are described in detail. The procedures apply to zircon, monazite, sphene, rutile, bad­deleyite, thorite, apatite, allanite, and gamet. Zircon in particular is carefully selected and generally air abraded, and is characterized using polishing and etching techniques. Reagent preparation and chemical processing are done in a clean air laboratory. Samples are spiked with a mixed 205Pb-233V-235V tracer, dissolved using steel jacketed Teflon pressure vessels or TeflonTM screw cap containers. U and Pb are separated using anion exchange resin columns. Blanks for typical sample amounts of O. 01 to 1. 0mg are less than J0pg V and 6-40pg Pb. Rapid JO minute mass analysis of the V and Pb are carried out using a Finnigan MAT 261 variable multicollector mass spectrometer solely in the static mode. Data reduction incorporates consideration of all sources of error in the analysis, and discordant V-Pb results are assessed on concordia plots using published regression techniques, taking into consideration the particular mineral systematics.
