Another One Bites the Dust!

I must have been good this past year, because Santa was very nice to me!.  The meteorite specimen she left this year is Dar el Kahal from Mali.  The fall was not observed, but the meteorite  was found in 2013. My new addition to the collection  is 540 grams, pretty dense.  The total mass of the meteorite wasScreen shot 2015-12-25 at 1.04.52 PM calculated at 85 kg, so I have about 0.6% of this particular find.

Ordinary chondrites are stony meteorites.  Stony meteorites make up almost 80% of all meteorite kinds, and that’s why they’re called “ordinary.” The two other major kinds of meteorites are iron (~8%) and stony-iron ~12%.)

Here’s the write-up by the Meteoritical Society:

History: A first individual, completely covered by black fusion crust, was found by a nomad while searching for historical artifacts near the former salt mines of Taoudenni, northern Mali. During the following systematic search many fragments totaling 85 kg were recovered from a strewn field about 10 km in diameter.

Petrography: The meteorite is an H type breccia consisting of completely recrystallized type 6 and less intensely recrystallized type 5 fragments. The latter contain delineated chondrules. The meteorite is strongly shocked (S4), i.e., olivine shows mosaicism.
