Lu-[sup.176]Hf geochronology of garnet I: experimental determination of the diffusion kinetics of [Lu.sup.3+] and [Hf.sup.4+] in garnet, closure temperatures and geochronological implications

The [sup.176]Lu-[sup.176]Hf and [sup.147]Sm-[sup.143]Nd decay systems are routinely used to determine garnet (Grt)-wholerock (WR) ages; however, the [sup.176]Lu-[sup.176]Hf age of garnet is typically older than the [sup.147]Sm-[sup.143]Nd age determined from the same aliquots. Here we present experi...
