Description: My name is Ruben Garcia - aka MrMeteorite - and I’m a meteorite hunter, dealer, and collector. I began my meteorite adventures in 1998 and since then I have found many thousands of meteorites as well purchased and sold many thousands more. I’ve been featured in many books and magazines about meteorites. Publications like Sky and Telescope, Discover, Iguana, Meteorite Times, and even the latest book by O. Richard and Dorothy Norton, called “What’s so Mysterious about Meteorites?” I’ve also been featured in such TV shows as, Cash and Treasures, Meteorite Men, Nova Science NOW with Neil deGrasse Tyson, and the United Stats of America - a program all about various statistics - with Sklar Brothers as hosts. Of course, I’ve also been the subject of newspaper articles all across the country as well as various NPR and BBC radio shows.

Abbreviation: NWA 12241 Observed fall: No Year found: 2018 Country: Algeria Mass: 1150 g Classification history: Meteoritical Bulletin: (2018) Martian (shergottite) Recommended: Martian (shergottite) This is 1 of 330 approved meteorites (plus 2 unapproved names) classified as Martian (shergottite). Comments: Approved 24 Nov 2018 Writeup Northwest Africa 12241 (NWA 12241) AlgeriaPurchased: 2018 Aug Classification: Martian meteorite (Shergottite) History: Purportedly found in Algeria and purchased by Mohamed Brahim Sueilem in August 2018 from a dealer in Bordj Badji Mokhtar, Algeria. Physical characteristics: The material (total weight 1150 g) comprises multiple broken fragments, some with adhering black fusion crust. The friable pieces are pale green in color and contain white plagioclase but no evident maskelynite. Petrography: (A. Irving and S. Kuehner, UWS) This fresh specimen has an orthocumulate texture with ~15 vol.% lath-like, birefringent plagioclase occurring interstitially to more abundant and coarser grained (0.2-1.6 mm, mean 0.7 mm) mafic silicate grains (unzoned olivine and patchily zoned low-Ca and high-Ca clinopyroxene with very limited compositional variation). Accessory phases include Mg-merrillite, chlorapatite, ilmenite, Ti-rich chromite, Cr-rich chromite and pyrrhotite (some associated with minor pentlandite). Levels of shock are judged to be low, based on the absence of optical effects in plagioclase and the complete lack of any conversion to maskelynite; the presence of widespread microcracks in mafic silicates is the only clear evidence of shock. Geochemistry: Olivine (Fa32.7-34.3, FeO/MnO = 47-48, N = 4), pigeonite (Fs25.0-30.4Wo5.5-10.0, FeO/MnO = 28-30, N = 4), subcalcic augite (Fs17.1-18.1Wo32.7-32.4, FeO/MnO = 23-25, N = 2), aluminous augite inclusion in olivine (Fs17.1Wo39.5, FeO/MnO = 28, TiO2 = 1.1 wt.%, Al2O3 = 6.2 wt.%), plagioclase (An43.0-57.8Or2.4-1.3, N = 3). Oxygen isotopes (K. Ziegler, UNM): analyses of acid-washed subsamples by laser fluorination gave, respectively, δ17O 2.907, 2.635, 2.808; δ18O 5.092, 4.620, 4.875; Δ17O 0.218, 0.195, 0.234 per mil. Classification: Martian (shergottite, olivine gabbroic, orthocumulate, low shock). Specimens: 22.4 g including one polished thin section at UWB; remainder held jointly by Naji Ben Faraji and Mohamed Brahim Sueilem.
