The application of a non-destructive analytical procedure to characterise the mineral phases in meteorites is a key issue in order to
preserve this type of scarce materials. In the present work, the Elephant Moraine 83227 meteorite, found in Antarctica in 1983
and originated from 4 Vesta asteroid, was analysed by micro-Raman spectroscopy, micro-energy-dispersive X-ray fluorescence
and the structural and chemical analyser (Raman spectroscopy coupled with scanning electron microscopy-energy-dispersive
spectroscopy) working in both point-by-point and image modes. The combination of all these techniques allows the extraction of,
at the same time, elemental, molecular and structural data of the studied microscopic area of the meteorite. The most relevant
results of the Elephant Moraine 83227 were the finding of tridymite for the first time in a 4 Vesta meteorite, along with quartz,
which means that the meteorite suffered high temperatures at a certain point. Moreover, both feldspar and pyroxenewere found as
the main mineral phases in the sample. Ilmenite, apatite, chromite and elemental sulphur were also detected as secondary
minerals. Finally, calcite was found as a weathering product, which was probably formed in terrestrial weathering processes of
the pyroxene present in the sample. Besides, Raman spectroscopy provided information about the conditions that the meteorite
experienced; the displacements in some feldspar Raman bands were used to estimate the temperature and pressure conditions to
which the Elephant Moraine 83227 was subjected, because we obtained both low and high formation temperature feldspar.
