Title: BILANGA: A UNIQUE DIOGENITE.
Author: S. E. Kolar , K. J. Domanik , D. S. Musslewhite , and M. J. Drake

Diogenites are a part of the howardite, eucrite, diogenite (HED) association. This group of meteorites is believed to originate from the large asteroid, 4-Vesta. These meteorites are typically very highly brecciated and contain 84-100 vol% orthopyroxene. Other common minerals include chromite as well as highly variable amounts of troilite and olivine. Silicate phases such as Ca-pyroxene, plagioclase, and silica are typically present in minor amounts and occur as small breccia fragments, exsolution lamella, or small single inclusions in orthopyroxene. As a result, few chemical analyses are available for these phases and their original textural relationship to orthopyroxene is poorly known

The Bilanga Diogenite fell on October 27, 1999 amongst and between the villages of Bilanga-Yanga and Gomposago, in Burkina-Faso.

The locals heard the reports associated with the fall and were pelted with rocks from the sky soon afterwards.
