HISTORY: Uruacu was first discovered in 1992 near Goias, Brazil. Only four masses were found on a farm by the owner of the property. The owner continued hunting for more meteorites for over a decade without any luck. Finally, after years of searching, in the past few years, the owner has located several other Uruacu specimens. The total known weight of this iron is still fairly low for an iron (probably only around 1500± hundred kilos), making this offering all the more rare of.
Uruacu is chemically similar to Campo del Cielo, however structurally it is not at all similar. It is a schreibersite and cohenite rich IAB that is extremely stable, and has beautiful etch patterns full of Neumann lines.
