Sueilila 005 24.658°N, 14.692°W Rio de Oro, Western Sahara Find: 2015-Apr Classification: Lunar meteorite (feldspathic breccia) History: The stone was found by two Moroccan hunters in April 2015 in a barren region. Further searching in the area led to the recovery of other similar-appearing stones totaling 15.6 kilograms, but this first stone was considered to be possibly different (because of the presence of some larger lithic clasts), and it was excluded from the classification of the other stones as a group under the name NWA 10495. Subsequently the first stone was sold by the finders to a Moroccan dealer, who in turn sold it in February 2018 at the Tucson Gem and Mineral Show to representatives of ArtAncient (a British antiquities dealer). Physical characteristics: A single, dark brown stone (282 g) lacking fusion crust but exhibiting a glossy weathering patina. Sawcuts reveal a very fine grained interior with diffuse larger whitish to black clasts. Petrography: (A. Irving and S. Kuehner, UWS; P. Carpenter, WUSL) Breccia consisting of sporadic gabbroic anorthosite and rare dunite clasts in a fine grained crystalline matrix. Minerals are anorthite, exsolved pigeonite, orthopyroxene, pigeonite, subcalcic augite, olivine, ilmenite, Ti chromite (with variable Ti content) and secondary barite. Geochemistry: Anorthite (An97.1-97.4Or0.0, N = 2), low-Ca pyroxene host (Fs50.1Wo6.0, FeO/MnO = 58), augite exsolution lamella (Fs25.1Wo40.9, FeO/MnO = 59), augite host (Fs26.6Wo40.2, FeO/MnO = 57), orthopyroxene exsolution lamella (Fs56.1Wo1.7, FeO/MnO = 55), orthopyroxene (Fs39.6-41.7Wo2.7-3.2, FeO/MnO = 59-63), pigeonite (Fs26.7Wo19.4, FeO/MnO = 55), subcalcic augite (Fs21.0-39.2Wo26.8-25.1, FeO/MnO = 46-59), olivine (Fa41.3-56.8, FeO/MnO = 89-99, N = 3), olivine in dunite clast (Fa46.7-48.0, FeO/MnO = 93-97, N =2). Classification: Lunar (feldspathic breccia). This specimen is from the same strewnfield as the NWA 10495 stones and is very likely paired with them. Specimens: 21.5 g in the form of two slices (one polished) at UWB; remainder with ArtAncient, Chelsea Creek, 31 Imperial Road, London SW6 2FR, UK. | ||||||||||||||||||||||||||||||||||||
