Kalahari 009

Kalahari, Botswana

Found 1999, September

Lunar meteorite (basaltic fragmental breccia)

A single stone of about 13.5 kg was found in September 1999 by an anonymous finder in front of a sand dune within the Kalahari desert, roughly 50 m apart from Kalahari 008. The rock is different to the Kalahari 008 anorthositic breccia. It has a heavily brecciated texture and is basaltic in composition. The sample does not contain solar wind implanted rare gases (L. Schultz, Mainz). Classification and mineralogy (Anna Sokol and Addi Bischoff, Mün): olivine, Fa50-99.9 (mostly Fa80-95); pyroxene is highly variable (Fs22-67 En10-64 Wo6-41); plagioclase An86-96 (very few plagioclase have more albitic composition, An70-80). The shock stage of the rock is S4; the weathering grade is W1; however, calcite veins are present. Oxygen isotopic composition: δ18O  = +6.87‰; δ17O = +3.45‰ (R. N. Clayton, Enrico Fermi Institute, University of Chicago, Chicago, U.S.A.); concentrations of selected elements (XRF or INAA; H. Palme, G. Weckwerth, Institut für Mineralogie und Geochemie, Universität zu Köln, Germany) in wt%: Al: 6.76; Mg: 5.14; Fe: 12.47; Ca: 7.66. Zr/Hf = 30.2 and Nd/Ta= 17.4 (Münker, Institut für Mineralogie, Universität Münster, Münster, Germany). Specimen: Type specimen, 20 g and polished thin section, Mün; main mass, anonymous finder.
