58Fe ratios of the double spike agreed. The composition of the double spike was then subtracted from the measured ratios, providing a new estimate of the Fe isotope composition of natural Fe, and the process was repeated to convergence. The data are reported in Table 1 in standard "delta" notation as a parts per thousand (per mil) deviation from the BIR-1 standard. All Fe isotope data listed in Table 1 are precise to 0.2 per mil or less at the 95% confidence level and represent the average of two complete procedural runs per sample.

4 product. These values are only slightly greater than the maximum 2σ precision of 0.2 per mil for the Fe isotope compositions reported in Table 1, and we suggest that this level of apparent fractionation is insignificant and not convincingly resolvable with our current analytical technique. Furthermore, the Fe isotope compositions of all product-reactant pairs listed in Table 1 are essentially identical within 95% confidence limits.
