Abstract

wo meteorites were found by anonymous finders in Western Sahara. One was purchased in 2016 at the Erfoud market by Hichame Mimaghador and the other one was purchased by Nicola Castellano at the Genova Mineral Fair in May 2017 from a Moroccan dealer. The main masses, weighing 1104 and 752 g, respectively, are markedly different from each since the first one is almost completely covered by black fusion crust and show cracks on the outer surface and the second instead has only small traces of fusion crust. The sawn surface of both show a chondritic texture, the first one almost without metal, the second with several metal spots. Both meteorites have been approved by the Nomenclature Committee of the Meteoritical Society with the names NorthwestAfrica11708and NorthwestAfrica12252,respectively. Boththemainmassesarewithowners.Thetypespecimens, weighing 24 and 41 g, respectively, and one thin section are on deposit at the Museo di Storia Naturale dell’Università di Firenze.
