英文摘要This study introduces a new zircon reference material, LKZ-1, for the in situ U-Pb dating and O-Hf isotopic and trace element analyses. The secondary ion mass spectrometric analyses for this gem-quality single-crystal zircon yielded a weighted mean Pb-206/U-238 age of 572.6 +/- 2.0 Ma (2 sigma, n = 22, MSWD = 0.90), with moderately high U concentrations (619 +/- 21 ppm, 1 SD), restricted Th/U ratios (0.146 +/- 0.002, 1 SD), and negligible common Pb content (Pb-206(c) < 0.2%). A comparable Pb-206/U-238 age (570.0 +/- 2.5 Ma, 2 sigma) was produced by the isotope dilution-thermal ionization mass spectrometry. The secondary ion mass spectrometric and laser ablation-assisted multiple collector inductively coupled plasma mass spectrometer analyses respectively showed that LKZ-1 had little variation in O (delta O-18(V-SMOW) = 10.65 +/- 0.14 parts per thousand; laser fluorination value = 10.72 +/- 0.02 parts per thousand; 1 SD) and Hf (Hf-176/Hf-177 = 0.281794 +/- 0.000016, 1 SD) isotopic compositions. LKZ-1 was also fairly homogeneous in its chemical composition (RSD of laser ablation ICPMS data <= 10%), displaying a relatively uniform chondrite-normalized rare earth element pattern ((Lu/Gd)(N) = 31 +/- 3, Eu/Eu* = 0.43 +/- 0.17, Ce/Ce* = 44 +/- 32; 1 SD). These consistencies suggest that the LKZ-1 zircon is a suitable working standard for geochronological and geochemical analyses.
