BILANGA Meteorite Amazing Piece I HED Diogenite Fall

Brought to you by: Top Meteorite

  • $ 6,900.00


On Offer: 153.9g amazing crusted piece of the Bilanga meteorite fall.
Type: Diogenite - Achondrite HED
Parent Body: Vesta or Vestoid
Description: 153.2 gram gorgeous end cut of Bilanga meteorite with amazing fusion crust.
Fell: October 27th, 1999
Location: Gomponsago and Bilanga-Yanga, in the country of Burkina-Faso. 
Event: The locals living in and around the villages of Gomponsago and Bilanga-Yanga reported hearing several load sonic phenomenon above, just before reporting  whizzing sounds in the air around them and then the ground being pelted with black glistening stones of many different shapes and sizes. Heavy cloud cover obscured the locals from observing the bolide and smoke trails usually associated with such an event. Achondrite meteorite falls are very rare and represent a fraction of a percent of all known meteorite falls, making this a very special event!
The HED Meteorites: The HED meteorite group is so named for the three types of meteorites that comprise the group; Howardite, Eucrite and Diogenite. The Eucrite and Diogenite are distinct meteorites, while the Howardite is a mix of the Eucrite and Diogenite lithologies. The HEDs are differentiated achondritic meteorites previously thought to originate from Vesta, but now leading researchers are starting to think they originated from a Vesta-like asteroid (not Vesta itself) that was destroyed long ago. This is because we also find iron meteorites with similar isotopic genetics as the HED, leading researchers to conclude the HED meteorites come from a large Vestan-like body that was in a large enough collision to also liberate pat or all of its metal core.

Achondrite (diogenite)

After a widely witnessed shower, at least 25 kg of meteorites with fresh black fusion crust were collected, comprising many stones.  Pieces are reported to have fallen in the villages of Bilanga-Yanga and Gomponsago (coordinates above apply to the latter).  Classi­fication and mineralogy (A. Bischoff, Mün):  a diogenitic breccia; Ca-poor pyroxene, Fs19–22, mean Fs20.5; plagioclase, An75–83; Ca-rich pyroxene is rare, one grain has En46.4Fs6.3Wo47.4. Oxygen isotopes (R. Clayton, UChi):  δ18O = +3.41‰, δ17O = +1.35‰.  Specimens:  7.5 kg, Casper; 4 kg, Heinlein; type specimen, 8 g, Mün; 25 g, NHM; 20 g, TCU; 80 g, Frei; 600 g, SI.
