Writeup from MB 112:
Northwest Africa 15972 (NWA 15972)
Morocco
Purchased: 2022
Classification: Ordinary chondrite (LL3)
History: Found in Morocco, and bought by Jean Redelsperger in Guelmim in 2022
Physical characteristics: Some fragments are partially crusted.
Petrography: (J. Gattacceca, CEREGE) Chondrite with packed chondrules ~800 µm set in a fine-grained matrix. Opaque minerals are metal and troilite.
Geochemistry: Olivine Fa14.2±8.1, range Fa0.4-29.9, Fa PMD 46% (n=18). Cr2O3 in ferroan olivine 0.157±0.089 wt% (n=17). Low-Ca pyroxene Fs8.4±3.5Wo1.8±1.4 (n=5).
Classification: Ordinary chondrite (LL3). LL group based on chodrule size and magnetic susceptibility. Subtype >based on the Cr2O3 content of ferroan olivine. Estimated subtype 3.2 based on the olivine Fa PMD.
Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.

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.

The Chelyabinsk meteorite fell on February 15, 2013 in Russia.
With a diameter of around 17 metres, the bolide fragmented in the atmosphere. The energy released by this phenomenon is equivalent to 30 times the Hiroshima bomb, creating enormous damage.
More than 1,000 people were injured as a result. Indeed, since light travels much faster (300,000 km/s) than sound (340m/s), people stood behind their windows to observe the light phenomenon, only for the shockwave to arrive a minute later, shattering hundreds of panes of glass and partially damaging a factory, causing many injuries from broken glass.
