Fall, 15 February 1814; 18 kg
Ordinary Chondrite (L6)

After detonations, an 18 kg meteoritic stone was recovered. Bachmut is one of several meteorites recovered in the early 19th century just after scientists realized that stones really do fall from the sky. While both chemical and mineralogical techniques were quite crude by contemporary standards, Bachmut itself appeared to be a reasonably normal well-equilibrated ordinary chondrite. The presence of olivine (Fa24), orthopyroxene, plagioclase, Fe-Ni metal, and troilite were reported very early. Compositional refinements have continued and a number of accessory minerals have since been discovered. Additional details related to the Fe-Ni metal, accessory sulfides, and chromite were reported by Ramdohr and several others. Most interesting, perhaps, are compositional complexities within the taenite-dominated Fe-Ni metal and an unusual chondrule with isotopically anomalous nitrogen and xenon.

Approximately half of the original main mass has been held at the University of Kharkov [Kharkiv] (as of 2000). The most important additional mass (1.6 kg) has been held at the Naturhistorisches Museum in Vienna.
