Iron meteorite, Octahedrite (IIIAB, Om)
Find, 1600; 10.1 tons

After the arrival of the Spaniards in the New World persistent reports of various large meteoritic iron masses eventually led to the recovery of several unusually large iron meteorites— including the Morito Iron, a ancient landmark in the vicinity of Hildalgo del Parral. The largely intact main mass — described by Buchwald (1975) as a 'beautiful conical monster' — is now on display in Mexico City, but a few pieces and fragments have been analyzed. The exterior displays fusion crust, troilite pits, and oxidized areas, but the interior is predominantly kamacite and taenite accompanied by plessite plus a few very minor accessories minerals. Various features indicate of preterrestrial shocks and deformation. Schreibersite is common as boundary precipitates and tiny rhabdites. Troilite is present as scattered nodules with twinned portions indicating plastic deformation. Exsolved Daubréelite accounts for ~10 vol% of the sulfide. Weatherates are common in some regions, particularly in surface pits and near surface veins.

As of late 2014, the IIIAB iron meteorites represent nearly 30% of all classified iron meteorites. Of these meteorites Morito is both the first recorded in (Western) scientific circles and the fourth most massive. The main mass is preserved at the School of Mines, Mexico City. However, a few specimens have been cut from it and listed under such names as Durango, Chihuahua, and Parral.
