The Tatahouine meteorite is a very beautiful achondrite diogenite meteorite, which fell on June 27, 1931 at 01:30 am, 4 kilometers northeast of the village of Foum Tataouine in Tunisia. The explosion woke up the whole population and also the French garrison. The next day French legionnaires found some fragments.
The diogenite meteorites come from the asteroid Vesta.
Nwa 13512 is an Aubrite meteorite discovered in Morocco near Boudnib in 2019.
I this date only 72 meteorites of this type have been classified.
It is a rare type of meteorite, difficult to find on the market.
The name Aubrites is linked to the fall of a meteorite in Aubres, France in 1836. They are composed mainly of orthopyroxene to enstatite.
History : Three visually-similar specimens (total weight 105 g)
found together near Boudnib, Morocco were purchased by Mohammed Hmani in December 2019.
Petrography: (A. Irving, UWS and P. Carpenter, WUSL) The specimen has a mean grainsize of ~400 µm and is composed predominantly of equant grains of enstatite with subordinate sodic plagioclase and accessory altered Si-bearing kamacite, altered Cr-troilite and schreibersite.
Geochemistry: Enstatite (Fs0.2±0.0Wo0.6-0.7, N = 3), plagioclase (Ab91.4An2.6Or6.0; Ab76.4An21.4Or2.3; N = 2), kamacite (Si = 1.5 wt.%, Ni = 7.9 wt.%).
Classification: Aubrite.
Specimens: 20.5 g including one polished thin section at UWB; remainder with Mr. M. Hmani.

Bechar 008 is a Howardite meteorite found in Algeria in July 2022 near Alagla.
Howardite meteorites come from the asteroid Vesta, which lies between Mars and Jupiter.

History: Found by Ahmed Dich and Hssain Azmamar in January 2021. Bought by Jean Redelsperger from Zaid Oualguirah in February 2021.
Physical characteristics: Partially crusted stone with a light grey interior
Petrography: (J.Gattacceca, CEREGE) Brecciated igneous rock with mineral and lithic gabbroic clasts. Main minerals are pyroxene (some exsolved) and plagioclase with grain size in the 100 to 500 µm range. Accessory minerals: metal (to 150 µm), chromite (to 100 µm), ilmenite (to 150 µm), troilite (to 200 µm).
