SIMS U-Pb zircon ages for the Upper Devonian Snobs Creek and Cerberean Volcanics from Victoria, with age uncertainty based on UO^sub 2^/UO v. UO/U precision
|
Abstract: Sensitive high-resolution ion microprobe (SHRIMP) zircon ^sup 206^Pb/^sup 238^U ages for the Snobs Creek Volcanics and the overlying Cerberean Volcanics in central Victoria are analytically indistinguishable at 373.2 ± 1.8 and 375.0 ± 2.0 Ma (2[sigma]). The SHRIMP data provide a refined numerical age for interbedded freshwater fish fauna of the Taggerty Formation and, together with its recently revised Givetian age based on independent faunal correlations, provide a new calibration point on the Devonian time scale. The use of Pb^sup +^/ UO^sub 2^^sup +^ rather than Pb^sup +^/U^sup ...
