Iron meteorite, Octahedrite (IID, Om)
Find, 1923; 454 kg, the most massive IID iron
A large mass of Fe-Ni metal (~10% Ni) was found by cowboys on the Alamo ranch northwest of Hermosillo. In 1928 Harvard purchased the meteorite and over the years several sections have been available for study. For an iron meteorite the mineralogy is somewhat nondescript. Underneath a residual limonitic fusion crust kamacite with Neumann bands and decorated boundaries is somewhat dominant. Taenite and plessite (~40 vol%) account for most of the remaining mass. Minor schreibersite in several morphologies and even less abundant troilite are also present. However, other reduces phases frequently found in irons are either sparse or missing. Oxides include both preterrestrial phases (chromite, cristobalite) as well as terrestrial weathering products (hibbingite and the limonitic crust). Carbo's relatively long exposure age (~ 700 Ma) suggests a long time as part of a very small meteoroid before its eventual collision with the earth,
Carbo is the most massive of the small group of IID irons (22 members) which account for ~2% of all recovered irons.
