The Allende meteorite fell in Mexico in 1969.
It is often considered as the “Rosetta Stone” of planetologists, because it has improved our knowledge on the origins of our solar system. This meteorite was formed before our planet, in the very first moments of the solar system. It preserves in its heart the traces of the nebula which generated the Sun and its procession of planets.

Aydar 003 is a very fresh carbonaceous meteorite of type CM1/2.
It is an extremely rare type, since to date only 26 meteorites of this type have been officially classified.
It was discovered in the Western Sahara in a concentration area called Aydar.
Aydar 003 27°40’06.09″N, 10°06’25.33″W
South, Morocco
Purchased: 2018
Classification: Carbonaceous chondrite (CM1/2)
History: Found between 2016 and 2018. Bought from Abdelaziz Alhyane.
Physical characteristics: Crusted stones. The fusion crust shows a network of cracks. Cut surface reveals dark interior
Petrography: (J. Gattacceca, CEREGE) Small altered chondrules (average apparent diameter about 270 µm) and altered mineral fragments and fine grained CAIs set in an abundant fine-grained phyllosilicate-rich matrix (about 75 vol%). Olivine has been almost entirely serpentinized. Opaque minerals are FeS and magnetite. No metal was found. Transmission Infrared spectroscopy (L. Bonal, IPAG) of matrix grains reveals a water and Si-O bands attributable to phyllosilicates.
Geochemistry: Olivine is serpentinized, with microprobe totals of 85.9%±1.1% (n=9). Unaltered olivine crystals give Fa1.4 and Fa 17.9 (n=2). Defocused (10 µm) microprobe totals in the matrix 75.5±5.5% (n=7).
Classification: Carbonaceous chondrite (CM1/2). Petrologic type 1/2 from the almost total serpentinization of silicates but absence of narrow -OH band typically seen in phyllosilicates of the smectite group commonly observed seen in type 1 chondrites. Possibly paired with NWA 11322 and NWA 8534.
Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.

The Orgueil meteorite is a meteorite that fell on May 14, 1864 in France in a field in the commune of Orgueil. It is a carbonaceous chondrite of type CI1, a very rare type. This is the first meteorite in which extraterrestrial amino acids have been found, giving credence to the theory of panspermia.
