“…In the sample digestion, alkaline fusion (Kleinhanns et al, 2002), lithium metaborate fusion (Bizzarro et al, 2003) and HF (Patchett and Tatsumoto, 1980;BlichertToft et al, 1997;Blichert-Toft, 2001;Lapen et al, 2004;Patchett et al, 2004) are used. The fusions have the disadvantage of higher blanks especially for Pb and Sr, although perfect isotopic equilibrium between sample and spike is expected, which is a prerequisite in ID.…”

A new preconcentration technique of Zr, Nb, Mo, Hf, Ta and W has been invented employing coprecipiation with Ti compounds. Silicate samples were digested by HF with addition of Ti. Subsequent drying with HClO 4 resulting in complete elimination of fluorine produces Ti compounds (oxide/hydroxides). The sample was then dissolved with dilute nitric acid and centrifuged, and the residual Ti compounds were collected. The Ti compounds forming from 2 mg of Ti without matrix elements concentrate 84-98% of Zr, Nb, Mo, Hf, Ta and W. In 20 mg basaltic and 50 mg peridotitic matrices, the addition of 1 mg of Ti was appropriate and gave yields of 46-69 and 54-79%, respectively, for Zr, Nb, Mo, Hf, Ta and W. Exploiting this preconcentration, sequential separation protocols of Hf, Pb, Sr, Lu, Nd and Sm for isotope analysis are developed with total blanks of 16, 11, 60, 2.4, 3 and 0.4 pg, respectively. The method is suitable for Lu-Hf system studies with capability of simultaneous separation of Pb, Sr, Nd and Sm from the same sample digest as well as isotopic anomaly studies of Zr, Mo and W. As application examples, accurate Lu-Hf data and Pb isotope ratios were obtained for basalt (JB-3) and peridotite (JP-1) by MC-ICP-MS.

Laburpena: Geokimika Isotopikoak/Geokronologiak azken hamarkadetan izan duen bilakaerak hainbat teknika analitikoren hobekuntza eragin du, gerriko metamorfikoen tektonikaren gaineko informazioan iraultza eraginez. Euskal Herriko Unibertsitatea (UPV/EHU) berariazko tresneria analitikoaren jabe da, munduan gehien erabiltzen diren metodo geokronologikoen inplementazioa eta hobekuntza ahalbidetuz. Lan honetan, Rb-Sr eta Lu-Hf sistemak MC-ICP-MS bidez analizatzeko metodologia garatu da alde batetik, eta Hf-Hf eta U-Pb sistemak LA-ICP-MS bidez neurtzeko teknikak bestetik. Teknika horiek Iberiar mendigunearen ipar-mendebaldeko Malpica-Tui eta Cabo Ortegal Konplexu Aloktonoetako presio altuko arroka metamorfikoen dataziorako eta trazaketarako erabili dira.Hitz gakoak: Geokronologia, masa-espektrometroa, arroka metamorfikoa. Abstract:The development of Isotope Geochemistry/Geochronology has triggered many technical improvements in the past decades and has revolutionised the potential information available on the tectonics of metamorphic belts.
