In a recent paper, Zhang et al. (2008b) described the results from an infrared (IR) spectroscopic study that addressed structural changes in a synthetic zircon (ZrSiO4) sample that resulted from the irradiation with heavy (i.e., 280 keV Pb+) ions. Infrared analyses of the same zircon sample have been also described by Zhang et al. (2008a). I see major problems with some of the interpretations presented in these two papers. Problems arise from the failure to consider the significant discrepancy between the sample volumes that were irradiated and analyzed, respectively. To illustrate the following discussion, a...
