“…A compilation of age‐indexed pre‐4.0 Ga zircon oxygen data (Table 2) with our new results is presented in Figure 4 [ Mojzsis et al , 2001; Peck et al , 2001; Cavosie et al , 2005; Valley et al , 2005; Nemchin et al , 2006b] along with lunar data for comparison [ Nemchin et al , 2006a]. The compilation includes only those zircon data accepted by various workers on the basis of separately established criteria regarding what constitutes “primary” oxygen isotope values.…”

“…The HfO 2 abundance in our primary zircon standard (AS‐3) is similar to JH and MN zircon compositions [ Cavosie et al , 2005; Maas et al , 1992; Crowley et al , 2005]. Nemchin et al [2006b] applied Hf‐related matrix effects corrections which were originally derived for high‐energy‐offset analyses [ Peck et al , 2001], in contrast to their low‐energy‐offsets. In the absence of observable matrix effects on our zircon standards, we applied no additional matrix effects corrections to the data.…”

“…The runs comprised a 90 second pre-sputter period with a raster of 20 μm, and field aperture centering using the 16 O signal followed by 64 seconds of data acquisition using two Faraday detectors in the multicollector system operating a common mass resolution of ca. 2500. Corrections for instrumental mass fractionation were determined using international reference material NBS-28 (silica sand), with further details given in refs 60 and 61. Full descriptions of all methods employed, including for Sr-, Nd-, and He-isotope analyses, are provided in the Supplementary Information.…”

“…The accessory mineral zircon found within these rocks can be dated using the U-Pb system and provides a temporal record of geochemical information (e.g., Hanchar and Hoskin 2003). Oxygen isotopes in zircon have been used to chronicle the maturation of Earth's crust throughout geologic time , elucidate the origins of granite (Kemp et al 2007), monitor differentiation of lunar crust (Nemchin et al 2006b), and demonstrate the presence of liquid water on the surface of Earth in the earliest Archean (Wilde et al 2001;Mojzsis et al 2001;Cavosie et al 2005). Although the concordance of U-Pb geochronology provides robust tests to evaluate post crystallization alteration, the oxygen isotope system contains no such safeguards and its resistance to chemical and physical alteration must be evaluated by other means.…”
