Tanezrouft 090 (Tnz 090) 25.163°N, 0.289°E Adrar, Algeria Find, possible fall: 2019 Oct 1 Classification: Ordinary chondrite (L6) History: On October 1, 2019, at around 11 pm, observers in the area south of Adrar, Algeria, witnessed a bright fireball event. After searching by hunters in the desert, multiple crusted and broken stones were found together on October 13 in an area close to Bir Zmila, northwest of the town of Ouallene. Naji Ben Faraji purchased the stones in Tindouf, Algeria on October 27, 2019. Physical characteristics: A total of 16 pieces ranging in weight from 43 g to 1489 g (combined weight 6219 g). Most of the broken stones are partially coated by fresh black fusion crust, and the interiors are overall light gray with visible fresh metal and some thin, black shock melt veinlets. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Very fresh, highly recrystallized specimen with very sparse remnant chondrules and partial chondrules. Much of the studied thin section exhibits a poikiloblastic texture. Accessory phases include lightly stained kamacite, taenite, troilite, chromite, chlorapatite and merrillite. Geochemistry: Olivine (Fa24.9±0.2, range Fa24.6-25.1, N = 6), low-Ca pyroxene (Fs20.7±0.3Wo1.7±0.1, range Fs20.4-21.1Wo1.6-1.8, N = 5), augite (Fs8.0±0.1Wo44.6±0.3, range Fs7.9-8.1Wo44.3-44.8, N = 3).
