- Descrição
- Bocaiuva iron meteorite (IAB) has been studied magnetically and metallographically in order to understand its stable natural remanent. magnetization (NRM). This meteorite consists in major amounts of 6-7wt% Ni kamacite associated with taenite, plessite, schreibersite and. magnetite for magnetic minerals. Tetrataenite, less than <math>0.2 %</math> in volume, is formed along the high Ni taenite lamellae and in the kamaçite domain walls. The NRM direction is almost parallel to a dominant plane of the tetrataenite development. Bocaiuva may have acquired the stable NRM during the slow cooling process under <math>300^oC\,\!</math> inside the meteorite parent body or after shock heating by collision.
