Crustal Evolution in the Southern Appalachian Orogen: Evidence from Hf Isotopes in Detrital Zircons

India's changing place in global Proterozoic reconstructions: A review of geochronologic constraints and paleomagnetic poles from the Dharwar, Bundelkhand and Marwar cratons

“…Data reduction and correction were conducted using a combination of in-house software and Isoplot (Ludwig, 1999). Additional details can be found in Mueller et al (2008).…”

Mesoproterozoic-trans-Laurentian magmatism: A synthesis of continent-wide age distributions, new SIMS U–Pb ages, zircon saturation temperatures, and Hf and Nd isotopic compositions

“…At the University of Florida (UF), Lu-Hf isotopic measurements were obtained on individual zircon grains using a Nu-Plasma MC-ICPMS equipped with a U-Pb collector block attached to a New Wave 213 nm ultraviolet laser. Analyses followed procedures described by Mueller et al (2008). Multiple analyses of the FC-1 zircon standard relative to 176 Hf/ 177 Hf = 0.28216 ± 0.00001 (2 S.D.)…”

“…These parameters are: present day depleted mantle 176 Hf/ 177 Hf = 0.28324; CHUR (BSE) 176 Hf/ 177 Hf = 0.282785; present day depleted mantle 176 Lu/ 177 Hf = 0.03867; CHUR (BSE) 176 Lu/ 177 Hf = 0.0336; and ( 176 Lu) = 1.867 × 10 −11 yr −1 . Nominal depleted mantle model ages were calculated on the basis of a model similar to that of Nowell et al (1998), as discussed by Mueller et al (2008). Two-stage "crustal" model ages (e.g., T CR ; Andersen et al, 2002) were calculated with assumed continental crustal 176 Lu/ 177 Hf = 0.0083 (upper continental crust, Rudnick and Gao, 2003) or 0.0150 (middle to lower crust).…”

Zircon U-Pb, Hf and O isotope constraints on growth versus reworking of continental crust in the subsurface Grenville orogen, Ohio, USA

“…Mueller et al (2008) shows that Grenvillian detrital zircon grains from a Pleistocene beach ridge in northern Florida, with an origin in the southern Appalachians, have a t DM of ca. 1.6 Ga, i.e.…”
