| contents | A mössbauer effect study of the soledade meteorite C. A. Samudio Pérez C. Paduani J. D. Ardisson Física, Astronomía y Matemáticas We performed aM¨ossbauer spectroscopy study of the iron meteorite Soledade. This meteorite, which consistsof a metallic matrix, is an octahedrite with polycrystalline troilite, cohenite, schreibersite and rhabdites as majorconstituents. A chemical analysis indicates 6.78 % Ni, 0.46% Co, besides traces of Cu, Cr, Ga, Ge, As, Sb,W, Re, Ir and Au. No traces of silicates have been found and no oxygen was detected. Iron is appearing in theausthenitic phase and alloyed with nickel. An analysis of the M¨ossbauer spectra at room temperature indicatesthat the Fe-Ni phase is homogeneously distributed in the matrix, although variations in the composition betweendifferent regions are observed. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435414 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.35 |
