Other/historical names associated with this locality:
Bonanza Iron meteorite; Butcher Iron meteorite
A sideritic meteorite, hexahedrite, Ni-poor, Type: IIAB
Found 1837; 2.1 tons
While numerous fragments have been reported since the original discovery, they are in the main — according to Buchwald — apparent components of an original single kamacite crystal. In addition to the dominant Fe-Ni metal, sectioning reveals troilite-daubréelite nodules and tiny schreibersite prisms. Other minor constituents (e.g., cohenite, copper) are also reported. Aragonite is from the clay soil in which the meteorite was found.
Also known as the Bonanza Iron and Butcher Iron. The largest mass (819 kg) is held at Harvard, but additional component masses of over 100 kg are held in Paris, London, Vienna and Washington.
