Description: NWA 15893 is an EH6 Enstatite chondrite meteorite, known for its classification as a rare and valuable specimen. This particular part-slice weighs 3.989 grams and features a fine polish on one side, enhancing its visual appeal. Along with its aesthetic qualities, it is accompanied by a Certificate of Authenticity (COA) card and a display case, making it a desirable addition to any meteorite collection. EH6 meteorites like NWA 15893 hold significant importance in the field of meteoritics due to their unique composition and rarity. Enstatite chondrites are a type of meteorite that primarily consists of minerals such as enstatite (a type of pyroxene) and olivine. EH6 chondrites specifically belong to a subgroup that contains a higher proportion of metallic Fe-Ni grains compared to other enstatite chondrites, making them distinct in terms of their chemical and mineralogical make-up. The rarity of EH6 meteorites like NWA 15893 adds to their scientific value as they provide insights into the early solar system and the processes that formed these ancient celestial bodies. Studies of EH6 chondrites have contributed to our understanding of the conditions present in the protoplanetary disk from which the Solar System formed, shedding light on the dynamics of planet formation and the materials that were present at that time. Overall, meteorites like NWA 15893 serve as important artifacts for scientific research, education, and as treasured collectibles for enthusiasts and collectors alike, highlighting the beauty and significance of these extraterrestrial remnants. Name: Northwest Africa 15893 This is an OFFICIAL meteorite name. Abbreviation: NWA 15893 Observed fall: No Year found: 2022 Country: (Northwest Africa) Mass: 3.4 kg Northwest Africa 15893 (NWA 15893) (Northwest Africa) Purchased: 2022 Classification: Enstatite chondrite (EH6) History: The meteorite was purchased from a meteorite dealer in Morocco. Physical characteristics: Dark brownish rock with some fusion crust. Petrography: The meteorite displays a fine-grained granular texture dominated by 20 to 300 µm sized enstatite and sodic feldspar grains. Opaque phases are Si-bearing kamacite, schreibersite, troilite, daubréelite, niningerite, and Cr-bearing troilite. No relict chondrules detected. Geochemistry: enstatite: Fs0.3±0.2Wo0.6±0.03 (Fs0.2-0.6Wo0.6-0.7, n=10); feldspar: An7.5±0.4Ab89.0±0.8Or3.5±0.7 (An7.0-7.9Ab88.1-90.3Or2.7-4.5, n=7); kamacite: Ni=6.48±0.15, Si=3.40±0.06, Co=0.29±0.01, n=5; troilite: Cr=0.77±0.18, Ti=0.24±0.017, n=5; (Mg,Fe,Mn)S: Fe=16.2±0.3, n=5 (all wt%) Classification: Enstatite chondrite (EH6a). EH designation based on silicon content in kamacite and presence of niningerite. EHa subgroup based on Cr contents in troilite, Fe contents in (Mg,Fe,Mn)S, and high abundance of daubréelite (Weyrauch et al,. 2017).
