Lot Essay

Several specimens of Uruacu were reported to have been found by cattlemen and gold prospectors in central Brazil in 1992. The meteorite contains moderately high contents of the iron carbide mineral cohenite as well as the iron-nickel phosphide mineral schreibersite. However, the bulk chemical composition of Uruacu is identical to that of the Campo del Cielo iron from Argentina and it seems likely that the two meteorites are paired. Like all iron meteorites, the specimen now offered originated from the molten core of an asteroid.
