(Northwest Africa)
Purchased: 2023
Classification: Mesosiderite
Physical characteristics: Dark brown stone
Petrography: (J. Gattacceca, CEREGE) Recrystallized igneous rock with triple junctions. Main minerals are pyroxene (to 200 µm), and plagioclase 60 µm in size. Opaque minerals are FeNi metal and troilite, and their weathering products. Silica polymorph and merrillite are observed. Despite pervasive weathering, the magnetic suscpetibility (log χ (× 10-9 m3/kg)=5.16) indicate an original high metal content on the order of a few tens of vol%.
Geochemistry: Pyroxene Fs32.0±1.0Wo3.8±0.5, FeO/MnO 23.9±3.3 (n=6). Plagioclase An93.5±2.4Ab6.3±2.4Or0.2±0.1 (n=3).

About Us

The WWMeteorites team (for "WorldWide Meteorites" - Meteorites from around the world) was created in 2003 with the primary goal of traveling around globe in search of these fascinating celestial objects, and make them available for Science... and Collectors. Since 2017, the team has established its base camp on the island of Unst (Shetland, UK).

With four or five trips per year on average, the number of finds (in countries as diverse as Tunisia, Spain, Qatar, the Sultanate of Oman ...) has quickly become important. WWMeteorites therefore collaborates with several laboratories that analyze, and classify the new meteorites, mainly the Museum Fur Naturkunde (Berlin), the CEREGE (University of Aix-Marseille), and the Appalacjain State University (North Carolina). WWmeteorites (under the name of its founder, Fabien Kuntz.)  have already more than 500 meteorites listed in the Meteoritical Society Database.

In order to have a classification and an official referencement established, as well as to allow the long-term research on the meteorites, a part of 20% of each find by WWmeteorites is deposited in a lab
