Non-destructive determination of 15 major and minor elements in murchison and allende meteorites using µXRF

Resumo

μXRF can efficiently and non-destructively aid the understanding of the chemical structure of the Murchison and Allende meteorites. In this study, was determined 15 major and minor elements (Mg, Al, Si, P, S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Fe, Zn) at meteorites carbonaceous chondrites. In addition, through the μXRF technique, it was also possible to obtain relatively precise qualitative data on where and how each of these chemical elements is related to Murchison and Allende meteorites. In this way, based on the results obtained, a brief comparative synthesis was made between the analysis of our results with some works selected from the scientific literature that use destructive analytical techniques to obtain these chemical elements. The comparative analysis demonstrates that the results were satisfactory and therefore, the use of μXRF appears to be efficient as a non-destructive analytical technique for the chemical analysis of these rare artifacts, which are meteorites
