EBSD Study of Fe-Ni phases on a L4-L5 ordinary chondrite meteorite
Almeida, B.; Seixas, T. M.; Mendes, M. H.; Ferro, M. C.; Salgueiro da Silva, M. A.; Santos, J. F.; Almeida, F.; Diogo, Z.; Lopes, A. B.; Vieira, J.The research on interplanetary materials such as comets, meteors or meteorites contributes to understand the origin and evolution of our Solar System. They provide highly valuable information on the relation between the conditions of formation and their microstructure, chemical composition and magnetic properties. Orientation relationships of the Fe-Ni system and distribution of body-centered cubic kamacite-α,...
XRD, SEM and petrologic characterization of stony-iron and metallic meteorites
Seixas, T. M.; Silva, M. A. S.; Almeida, F.; Diogo, Z.; Mendes, M. H.; Santos, J. F.; Vieira, J. M.; Marques, M.Meteorites are remnants of geological processes that occurred in our Solar System. Properly analyzed, the bulk composition, mineralogy, and petrology of meteorites can be used to constrain planet formation processes. Moreover, the laboratorial characterization of meteorite samples plays an important role in the interpretation of asteroid remote observation spectra. In this work, we have characterized three mete...
