Ksar Ghilane 021 H5 #5 – 6,2 g
37,20€Ksar Ghilane 021 est une météorite de type H5 que j’ai trouvée avec mon ami voyage Claude Roy lors d’une expédition en Tunisie près de l’Oasis de Ksar Ghilane le 13 février 2020, juste avant la pandémie de Covid 19.
A ce jour seulement 80 météorites ont été découvertes en Tunisie.

NWA 14826 LL3 #6 – 2,1 g
100,80€NWA 14826 est une belle chondrite de type chondrite LL3 de seulement 129 grammes.
Cette météorite a la particularité d’avoir des inclusions carbonées et achondrites sur certaines tranches.
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. |
