Iron meteorite, octahedrite (IIIAB, Om)
Fell,1890; 600 kg, 1 piece.
The Jianshi meteorite fell in 1890, but knowledge of this rather large iron fall has only gradually become known to the worldwide scientific community with announcements such as the report on Chinese meteorites by Depel (1981). As expected for a IIIAB octahedrite (8.5% Ni), Jianshi contains kamacite, taenite, and plessite associated with its Widmanstätten structure. Accessories such as cohenite and troilite are present as well. Iron oxides (magnetite and limonite) and unidentified silicates are also reported. Some of the cited sources provide English abstracts, but a full report on this meteorite in an English venue will require knowledge of both Chinese and English.
While Jianshi is only the 60th most massive iron meteorite recovered by late 2014, it is the second-most massive witnessed iron fall. Only the 1947 Sikhote-Alin fall was more massive. Jianshi is also the most massive of eleven witnessed IIIAB falls.
The main mass has been left at its fall site.
