dc.description.abstractHere we report oxygen isotopic compositions (both δ18O and δ17O) of San Carlos olivine, Juan de Fuca basalt glass, garnet standard at University of Wisconsin (UWG-2 garnet), National Bureau of standard #28 quartz (NBS-28 quartz), a hydrothermal quartz from China (CQ4 quartz), chert flint standard and a serpentine measured with a CO2-laser BrF5 fluorination system installed at Korea Polar Research Institute. In addition we measured VSMOW (Vienna standard mean ocean water) and SLAP (standard light Antarctic precipitation) with the same line;a scaling factor of 1.056 was obtained to fit the measured SLAP data to the recommended value of δ18OSMOW = ?55.5‰. All the other data were corrected using the VSMOW-SLAP scaling factor. Majority of the samples in this work have been measured by several laboratories;our data in general agree very well with previous data. We report data using the delta prime notation, since linearity of a mass-dependent fractionation line holds in δ17O vs. δ18O diagram for wide range of oxygen isotopic compositions. Average δ18O values and 2σ standard error of means are 5.27 ± 0.04‰ for San Carlos olivine, 5.49 ± 0.02‰ for Juan de Fuca basalt glass, 5.73 ± 0.05‰ for UWG-2 garnet, 9.18 ± 0.08‰ for NBS-28 quartz, 23.14 ± 0.36‰ for CQ4 quartz, 33.97 ± 0.16‰ for chert flint standard and 0.78 ± 0.07‰ for the serpentine.
