U-Pb zircon in situ dating with LA-MC-ICP-MS using a mixed detector configuration

Chemale, Farid Jr.; Kawashita, Koji; Dussin, Ivo A.; Avila, Janaina; Justino, Dayvisson; Bertotti, Anelise Losangela

Description

The LA-MC-ICP-MS method applied to U-Pb in situ dating is still rapidly evolving due to improvements in both lasers and ICP-MS. To test the validity and reproducibility of the method, 5 different zircon samples, including the standard Temora-2, ranging in age between 2.2 Ga and 246 Ma, were dated using both LAMC- ICP-MS and SHRIMP. The selected zircons were dated by SHRIMP and, after gentle polishing, the laser spot was driven to the same site or on the same zircon phase with a 213 nm laser...[Show more]
