Miller Butte 03002: a new rare iron meteorite (IID) from Antarctica
The Miller Butte (MIB) 03002 iron meteorite was found during the XIX (2003–2004) Antarctic campaign of the Italian Programma Nazionale delle Ricerche in Antartide (PNRA) in northern Victoria Land (Antarctica). MIB 03002 is classified as a medium octahedrite belonging to the rare IID chemical group,...
