Find: 1 July 1 2007
Iron, medium octahedrite (IIIAB)
History: Four small fragments were found buried adjacent to a circular depression by two local residents using a metal detector. The circular depression was subsequently confirmed as a 36 m diameter Late Holocene impact crater based on morphology, identification of impact ejecta and crater fill, and presence of impact melt (C. Herd and D. Froese, University of Alberta), and further fragments were recovered.
Physical characteristics: The meteorite consists of 74 samples with a total mass of 5372 g. The samples were found buried up to 25 cm and have a red-brown exterior.
Petrography: (C. Herd, University of Alberta, UAb) Widmanstätten pattern with an average bandwidth of 0.8 ± 0.2 mm and areas of plessite are evident on polished and etched surfaces. Locally, kamacite lamellae are coarser and taenite lamellae are offset as a result of shock deformation and recrystallization. Rare Fe-Ni phosphide inclusions are present.
Mineral compositions and geochemistry: Bulk composition: INAA data (J. Duke, UAb): Ni = 8.11 ± 0.13 wt%, Co = 4950 ± 100 μg/g, Ir 10.3 ± 0.5 μg/g, (uncertainties 1σ, 68% confidence level), Ge ≤ 40 μg/g, indicate the IIIAB group.
Classification: Iron, IIIAB medium octahedrite, extensive shock, moderate weathering.
Type specimens: A total of 2.4 kg is on deposit at UAb. The remainder of the known material is held by the anonymous finders.

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
