From the MetBul:

History: On the evening of November 16, 2021, around 9:30 pm, a fireball was seen by many people in the area of Guelmim and Tan-Tan, Morocco. Field investigations were conducted in December by H. Chennaoui Aoudjehane, M. Aoudjehane, L. Zennouri (FSAC and ATTARIK), A. Bouferra and a team from the Moroccan Association of Meteorites to obtain the coordinates of the fall and testimonies of eyewitnesses. Only one explosion was heard and a white color was reported for the visible meteor. Eyewitnesses from Msied village said it was like a broken lightning in the evening lasting 2 or 3 ", moving from north to south and stopping by the mountains. The first stones were found on December 4 following rainfall in the province. Only a few pieces were found totaling less than 2 kg. The strewnfield is about one km long in concordance with a direction north to south reported by eyewitnesses.

Petrography: This specimen is a breccia composed of equilibrated chondrite clasts of various petrologic types. Type 4 clasts consist of well-formed chondrules in a relatively coarse-grained matrix, whereas Type 5 clasts contain fewer well-formed chondrules, and Type 6 clasts are largely recrystallized with only a few relict chondrules and holly leaf-shaped metal grains. In between these lithic clasts is a sparse opaque, very fine grained matrix. Some of the metal in the studied thin section exhibits very slight staining by terrestrial Fe oxides.
