This 2023 synopsis from the All-Domain Anomaly Resolution Office (AARO) in the Office of the Secretary of Defense covers Oak Ridge National Laboratory's analysis of a layered magnesium-zinc specimen with bismuth and lead bands. The specimen is claimed to come from a UAP crash around 1947 and to act as a terahertz waveguide. Microscopy, spectroscopy and isotope analysis found that its magnesium and lead signatures are terrestrial and that its impure, layered bismuth could not have worked as a waveguide.

The figures plot the δ26Mg′ vs. the δ25Mg′, which represent the differences in 26Mg/24Mg and 25Mg/24Mg isotopes relative to a known standard (DSM-3) in parts per thousand (‰) notation. This calculation adjusts for known instrumental mass bias effects inherent in ICP-MS analyses and is consistent with how magnesium data in literature are often presented. (Top) The extreme magnesium isotope compositions possible from different star types. (Bottom) A zoomed-in view of the magnesium isotope compositions of local solar system materials and the material in question. Uncertainty envelopes are not included, but when plotted with their uncertainties, data points overlap the kinetic and equilibrium fractionation lines. (Note: Data points shown with a diamond shape, included for completeness, were extracted from an older analysis source; we cannot directly verify the precision or correctness of these data. The delta values were calculated relative to DSM-3, and a systematic offset correction factor was applied; error012 Page determined to be Unclassified Reviewed by Chief of Staff, AARO IAW FY24 NDAA, Section 1841 (a)(1)(C) Date: 02/06/2025 bars for these points reach ± 2 ‰ uncertainty.)
