Iron meteorite, ungrouped (I-ung, Off)
Found 1863; ~22 tons
A very large, irregularly shaped mass of Fe-Ni metal (9.7 % Ni) found in a Sinaloa cornfield and was eventually brought to a museum in Culiacan after several ~ 1 kg masses had been distributed in both Europe and the Americas. While a large piece seems to have fallen off in flight and a large crack had developed, the meteorite apparently arrived on earth as a relatively intact mass before partially burying itself in the ground. The mass is dominated by fine kamacite and taenite lamellae accompanied by conspicuous plessite and minor schreibersite. Very minor amounts of troilite and daubréelite are also present. Neumann bands, martensite, and other features due to shock are present.
Bacubirito is the most massive of 117 ungrouped irons â those irons which do not belong to any of the 13 currently defined Geochemical Groups of iron meteorites. However, very little scientific work concerning Bacubirito has been reported in recent decades.
