Comment:
(a) 176Yb/177Hf=(176Yb/173Yb)true x (173Yb/177Hf)meas x (Mi73(Yb)/Ml77(Hf))^Hf^ P(Hf) = ln(179Hf/177Hf true/179Hf/177Hfmeasured)/ln (M179(Hf)/M177(Hf)), M = mass of respective isotope. The 176Lu/177Hfwere calculated in a similar way by using the 175Lu/177Hfand (3(Yb). Quoted uncertainties (absolute) relate to the last quoted figure. The effect of the inter-element fractionation on the Lu/Hfwas estimated to be about 6% or less based on analyses of the GJ-1 and Plesovice zircons.
(b) Uncertainties are quadratic additions of the within-run precision and the daily reproducibility of the 40ppb-JMC475 solution. Uncertainties for the JMC475 is 2 standard deviation,
(c) Initial 176Hf/177Hf and epsilon Hf calculated using the age determined by LA-ICP-MS dating (see column f), and the CHUR parameters: 176Lu/177Hf= 0.0336, and 176Hf/177Hf=0.282785 (Bouvier et al., 2008).
(d)Two stage model age in billion years using the measured 176Lu/177Lu of each spot (first stage = age of zircon), a value of 0.0113 for the average continental crust (second stage), and a depleted mantle 176Lu/177Hf and 176Hf/177Hf of 0.0384 and 0.28325, respectively (see Gerdes and Zeh, 2006 for details and references),
