“…In this section, we report HH‐ED‐XRF Fe and Mn abundances of the interior and fusion crust for six meteorite ‘falls’ (five SNCs and one HED) and two ‘finds’ (the Saharian DaG 669 and the Antarctic Allan Hills 76005) (Table and Figure ). As all Fe and Mn K α radiations are detected approximately within the first 100–500 μm below the sample surface (Potts ), we are confident that the measured Fe and Mn values represent the actual fusion crust values. The composition of fusion crusts for five HEDs and one SNC obtained by Genge and Grady () and Gnos et al .…”

We evaluate the potential of a hand-held energy dispersive XRF spectrometer for the preliminary classification of non-chondritic differentiated meteorites. The studied achondrites include nine lunar meteorites, seventeen Martian meteorites, five angrites and eighteen meteorites from asteroid 4 Vesta. Analytical precision and accuracy was tested on thirty-nine terrestrial igneous rock slabs with a wide range of composition. Replicate analyses, performed on the studied meteorites, show that Fe/Mn values together with Si and Ca/K ratio can be used in the discrimination of different achondrite groups. Fusion crust's Fe/Mn values of meteorites from Vesta and Mars are indistinguishable from those of the interior implying that even measurements on the fusion-crusted external surface could be sufficient to pigeonhole non-chondritic meteorites. Hand-held energy dispersive XRF spectrometer is a non-destructive but very effective technique for preliminary classification of achondrites in the field and in laboratory and for the identification of mislabelled meteorites in museum collections

A LiFZOO analyzing crystal, which was treated to enhance heavy element sensitivity, was evaluated for application to the analysis of geological silicate materials prepared as pressed pellets. The treated crystal produced up to two-fold higher sensitivities along with backgrounds which were approximately two-fold higher. Lower limits of detection were produced, and the treated crystal is recommended for the routine determination of the elements Ni through Nb using K emission and for elements having L emissions in the same energy range. The limit of detection for Nb was reduced from 0.9 to 0.6 ppm (100 s data acquisition) when the treated crystal was used in place of the standard crystal. For elements with lower emission energies, there was a smaller, but significant, lowering of the limit of detection when the treated crystal was used. The advantage of the treated crystal decreased as the emission energy decreased.
