Ksar Ghilane 021 is a meteorite of type H5 that I found with my travel friend Claude Roy during an expedition in Tunisia near the Oasis of Ksar Ghilane on February 13, 2020, just before the Covid 19 pandemic.
To date only 80 meteorites have been discovered in Tunisia.

NWA 14826 is a beautiful LL3 chondrite of only 129 grams.
This meteorite has the particularity to have carbonaceous and achondrite inclusions on some slices.
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.
