Iron meteorite, Octahedrite (IIIAB, Om)
Find, 1867; 1.545 tons
A large lenticular mass of meteoritic iron was found wrapped and entombed in the Casas Grandes ruins on the Rio de las Casas Grandes. While the exterior is corroded, etched WidmanstÀtten patterns exhibit distinct long lamellae accompanied by profuse, often deformed Neumann bands. Taenite and plessite occupy ~40 vol% with some martensite and poorly resolvable "black taenite" also present. Accessory schreibersite is common as blebs in the comb plessite and as boundary precipitates. Troilite with very minor daubréelite and carlsbergite are also present. Graphite was reported by Tassin (1902), but was not observed by Buchwald (1975).
Casas Grandes is the 7th most massive of the 11 IIIAB irons with a mass of over one ton. The 299 recovered IIIAB irons represent the most numerous iron group recovered by the end of 2014 (27% of recovered irons). The IAB irons (n= 274) are nearly as numerous. The main mass has been held at the Smithsonian National Museum (Washington).
'Casas Grandes' is the name listed at the Meteoritical Bulletin Database and in the Catalogue of Meteorites (2000). 'Chihauhau' is also a recognized synonym used in the past.
