%X brazil has 58 cataloged meteorites for scientific studies; a low number compared to countries in europe and the united states. the samples studied belong to a collection of 17 meteorites from the mineralogy museum professor djalma guimar£¿es - mmpdg in belo horizonte, minas gerais. ten of those meteorites were found in brazil; among them are the bocai¨²va and jo£¿o pinheiro meteorites. the bocai¨²va meteorite, the third heaviest (64kg), was found around 1947 in the town of bocai¨²va, located 384km from belo horizonte, in the state of minas gerais. besides the bocai¨²va meteorite, there is also, in the mmpdg, another fragment cataloged as "bocai¨²va meteorite", which is actually a fragment from a different meteoritic body, called jo£¿o pinheiro, yet to be cataloged. the mineralogical differences, especially regarding the silicate portions of the bocai¨²va, as well as fluid and melted inclusions, leave no doubt that they belong to different meteorites. minerals such as kamacite, taenita, troilite, schreibersita and graphite are found in the jo£¿o pinheiro meteorite, while in bocai¨²va are present forsterite, kamacite, taenita, troilite, schreibersite, pentlandita, magnetite, chromite, pigeonite, diopside, enstatite, plagioclase, apatite, calcite and goethite.
