Writeup from MB 111:
Northwest Africa 14826 (NWA 14826)
(Northwest Africa)
Purchased: 2021
Classification: Ordinary chondrite (LL3)
History: Bought by Isabelle Pothier in 2021
Physical characteristics: A single stone without fusion crust
Petrography: (J. Gattacceca, CEREGE) Chondrite with packed chondrules with average apparent diameter 1190±530 µm (n=21) set in a rare fine-grained matrix. Olivine is zoned. Opaque minerals are metal and troilite. Some chondrules are rimmed with metal and troilite. A 1 cm sized chondrule is visible in the studied section.
Geochemistry: Olivine Fa15.0±8.7, range Fa0.8-28.0, Fa PMD 52% (n=9). Cr2O3 in ferroan olivine 0.28±0.09 wt%. Low-Ca pyroxene Fs4.6Wo0.4 (n=2).
Classification: Ordinary chondrite (LL3). LL group based on magnetic susceptibility and chondrule size. Cr2O3 content of ferroan olivine suggests a low petrographic subtype.
Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.

El Blida 006 is an oriented meteorite of 97 grams of type LL7. It was discovered near Zagora in Morocco in 2020 by Ahmed Najii.
It is a strongly crystallized brecciated meteorite with a beautiful fusion crust.
I sell the main mass of 74 grams, the rest was used for the classification, so it is a unique piece !

Kheneg Ljouad est une météorite de 10 kg tombée au Maroc, elle a été classifiée chondrite de type LL5/6.
This is the only fall observed of this classification.
On Wednesday, July 12, 2017, at approximately 11:13 p.m. Moroccan summer time (GMT+1,) a bright fireball was widely seen throughout southern Morocco.
The fireball lasted several hours and was followed by a series of bangs heard throughout southern Morocco. This event was later reported by the national television channel). The site of the fall is in a militarized area of Morocco, but close to the border with Algeria. The military and nomads were the first to arrive at the site of the fall and the first piece was found within 12 hours of the fireball on July 13. A field mission was organized by H. Chennaoui Aoudjehane (FSAC), M. Aoudjehane, A. Bouferra and H. El Harbi on Saturday, July 15 to collect information on the fall and samples for classification and submission. The team obtained permission to enter the militarized zone and went to the fall site on July 16. The team encountered several hunters with fresh, black, fusion crusted stones.
History: Found in september 2018 by Hammo Oulguirah. Bought in Agadir from finder.

Rare relict chondrules. Plagioclase is found as euhedral grains and as veins between the other silicates. Ca-phosphates to 200 μm. Chromite to 50 μm. Metal as small blebs or elongated grains in the olivine.
Geochemistry: Olivine Fa 32.0±0.4 (N=4). Orthopyroxene Fs26.4±0.2 Wo1.9±0.5 (N=3). Plagioclase An10.4Or5.1 (N=3). Chromite Cr#=0.88. Magnetic susceptibility log χ =3.55 (χ in 10-9 m3/kg).
