| dc.description | A microscopic and electron microprobe study of the Sete Lagoas chondrite shows that based on the compositions of olivine (Fa19.4), orthopyroxene (Fs17.1), and chromite, the chondrite belongs to the H-group. A well-developed chondritic texture, combined with slight variations in the compositions of ferromagnesian minerals, as well as the presence of glassy material (particularly in chondrules), suggest that the meteorite belongs to the petrologic class H4. | en-US |
| dc.description | O estudo microscópico e por microssonda eletrônica do condrito Sete Lagoas mostra que, com base na composição química da olivina (Fa19,4), do ortopiroxênio (Fs17,1) e da cromitaro meteorito enquadra-se perfeitamente no Grupo H. A textura condrítica bem desenvolvida, a presença de material vítreo (particularmente no interior dos côndrulos), aliadas às pequenas variações químicas dos minerais ferromagnesianos, são sugestivas de que o meteorito pertence à classe petrológica H4. | pt-BR |
