Le samedi 11 mars 2023, vers 10h30 heure locale, plusieurs témoins oculaires d’Algérie et de Mauritanie ont rapporté avoir vu une boule de feu brillante s’approchant du nord au sud à une vitesse relativement élevée et avec un angle d’entrée faible.
Les habitants de la ville d’El Menia en Algérie ont rapporté avoir entendu un bang sonique suivi de pierres frappant le sol.
Le poids total connu est estimé à environ 75 kg.
Tisserlitine 001 est classifiée comme une météorite lunaire de type brèche régolithique feldspathique.
Tisserlitine 001 a été trouvée au Mali en 2019 dans la région de Kidal. Le poids total récupéré est de 57,41 kilogrammes.
Une altération et un remplacement des minéraux sont observés dans la Tisserlitine 001 et semblent être le résultat de processus hydrothermaux.
Dans un ciel dégagé, une boule de feu, suivie d’une traînée de fumée est aperçue au-dessus de La Havane à Cuba, puis est tombée au sol sous forme d’une pluie de fragments dans la vallée de Vinales, à 180 km de la capitale, dans l’ouest du pays… Tombée vers 13 h 30 heure locale, le 1er février, sans causer de victimes, la chute de la météorite était accompagnée d’un éclair et d’une forte explosion.

Amgala 001 26.014°N, 11.020°W
Saguia el Hamra, Western Sahara
Purchased: 2022 Dec
Classification: Martian meteorite (Shergottite)
History: Multiple stones were found together in December 2022 near Meharrize. Said Muftah Bachir and Ziyao Wang bought 12 kg together from the finders, including the largest 5200 g individual; Mark Lyon acquired 19165 g from two different dealers; Aziz Habibi obtained 3500 g from another dealer.
Physical characteristics: Weathered exterior surfaces of the stones are brown with a distinctive knobby appearance. Fresh interiors are greenish-gray with darker olivine phenocrysts visible.
Petrography: (A. Irving, UWS, and P. Carpenter, WUSL) Zoned olivine phenocrysts (up to 2 mm in length) are set in a groundmass with variable grainsize composed predominantly of prismatic, zoned clinopyroxene and lath-like maskelynite, together with accessory alkali feldspar, pyrrhotite, ulvöspinel, chromite (with variable Ti content), ilmenite, baddeleyite and chlorapatite. Thin opaque shock veins crosscut the specimen as well as secondary calcite veinlets. Olivine phenocrysts contain small patches of alteration products (red-brown in thin section).
Geochemistry: Olivine (Fa31.7-56.6, FeO/MnO = 52-55, N = 5), pigeonite (Fs27.7-48.4Wo10.4-9.8, FeO/MnO = 29-35, N = 3), subcalcic augite (Fs20.7-30.4Wo32.5-34.6, FeO/MnO = 28-32, N = 2), maskelynite (An47.4-50.5Or2.2-1.7, N = 2), alkali feldspar (Ab49.4Or34.0An16.7).
Classification: Shergottite (olivine-phyric).
Specimens: 68.3 g including one polished thin section at UWB; remainder with Mr. S. Bachir/WangZ (12 kg), Mr. M. Lyon (19165 g) and Mr. A. Habibi (3500 g).
