The screenshot shows the readout from a XRF analysis of a sample labeled "Low Karat." The table lists elements along with their respective percentages and uncertainties (±s±s).
Fe (Iron): 84.70% ± 0.07% Ir (Iridium): 8.16% ± 0.04% Cu (Copper): 3.63% ± 0.03% Ag (Silver): 2.91% ± 0.02% Au (Gold): 0.89% ± 0.02% Ni (Nickel): 0.78% ± 0.02%
The sample is predominantly composed of iron, as it constitutes 84.70% of the material.
Iridium is present at 8.16%. The high percentage of iridium is unusual and warrants further investigation as its typically very rare and expensive, and especially rare for what is known about the geology and geography. The accuracy and possibility of errors like spectral overlap or interference should be considered and cross-referencing with other analytical methods like lab assays will be crucial if not done already and kept private.
