The Atacamaites were discovered in the Atacama desert in Chile.
They are black and glassy objects of about 1 cm, they were formed following an impact about 7.8 million years ago.
Their small size, heterogeneity, state of oxidation and level of contamination distinguish them from tektites, which is why a study conducted by J. Gattacceca, Bertrand Devouard, Jean-Alix J-A Barrat, Pierre Rochette, M.L. Balestrieri, G. Bigazzi, G. Ménard, F. Moustard, E. dos Santos, R. Scorzelli, proposes to name them “tektoids”.
The impactor was an iron meteorite, most probably of the IIAB group.

Fezzou 001 is a rare R4 rumuruti chondrite meteorite.
Weighing just 154 grams, it was discovered in Morocco by Rjdali Hmou and Mohamed Taouch on August 1, 2018. This rumuruti has the particularity of being slightly magnetic and not brecciated.
In April 2013, I went meteorite prospecting in Morocco with a group of friends.
After an unsuccessful search for the Martian meteorite NWA 7397, we met a group of meteorite hunters who took us to the site of a new meteorite discovery on April 18.
The day before, a 219-gram meteorite had been found, and the meteorite hunters initially thought it was a lunar meteorite.
It turned out to be not a lunar meteorite, but an eucrite.
Other fragments will be discovered later including the supposed main mass (332.85 grams) on April 24, 2013 by Lahcen Oukhouya meteorite hunter and native of Smara.
I was able to acquire the main mass of this fall, as well as 8 other fragments through Ali Oulmaleh (meteorite dealer in Erfoud) and Mohamed Elguirah (meteorite hunter in Tan Tan).
This meteorite was found 120 km northeast of Laayoune in the Western Sahara, in a place called Chwichiya (little fez) in reference to the mountain seen in this region in the shape of a fez.
Chwichiya is an area rich in meteorites, and in particular achondrites, 4 different achondrites have been discovered within a radius of 6 kilometers!
This meteorite is a brecciated eucrite, composed of 11 pieces for a total of 1038 grams. This meteorite has the particularity to have two different textures.
Petrography: Breccia with coarse basaltic clasts in a fine-grained matrix. The matrix has a doleritic texture with plagioclase grain size of several mm. Dominant minerals are exsolved pyroxene and mm-sized calcic plagioclase laths. Minor phases include chromite, silica, Ca-Phosphate, troilite and metal.
Trinitite is a glass made during the first nuclear explosion called Trinity, in Alamogordo, New Mexico on July 16, 1945.
Trinitite is made from the vitrification of the desert sand linked to the different elements of the structure on which the bomb rested and the bomb itself. Recently, researchers discovered that a piece of red Trinitrite took the form of a quasicrystal.
First discovered in the laboratory in the 1980s, quasicrystals also occur in nature, notably in meteorites.

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.
