Writeup from MB 83:
Gao-Guenie, new name With the recent paper by Bourot-Denise et al. (1998), the Meteorite Nomenclature Committee has decided that a new, collective name, Gao-Guenie, will be bestowed upon all meteorites formerly identified as either Gao (Upper Volta) (frequently truncated to Gao) or Guenie. It had been reported that two meteorite showers occurred one month apart in 1960 in the country now known as Burkina Faso. But the new work confirms long-held suspicions that the two meteorites are indistinguishable from each other and that there was most likely only one fall (1960 March 5).  The confusion about this meteorite has been compounded by the fact that new stones continue to be found ~40 years after the fall and are given arbitrarily one or the other name. Henceforth, the official name for all meteorites from this shower will be Gao-Guenie, with the names Gao (Upper Volta) and Guenie as recognized synonyms.

 

 

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
