Writeup from MB 89:
Found 1999, September
Lunar meteorite (feldspathic regolith breccia)
A single stone of 598 g was found in September 1999 by an anonymous finder in front of a sand dune within the Kalahari desert. The rock is an anorthositic breccia having typical clasts of lunar highland breccias (e.g., feldspathic crystalline melt breccias, granulitic lithologies, cataclastic anorthosites etc.) embedded within a well-lithified matrix. An impact melt spherule indicates that this rock derives from the regolith. The regolith origin is also supported by the finding of solar wind implanted rare gases (L. Schultz, Mainz). Classification and mineralogy (Anna Sokol and Addi Bischoff, Mün): olivine, Fa63±18; pyroxene Fs42±10; plagioclase An85-98. The shock stage of the rock is S4, the weathering grade is W1. Oxygen isotopic composition: δ18O = +6.52‰; δ17O = +3.32‰; Δ = -0.07‰ (R. N. Clayton, Enrico Fermi Institute, University of Chicago, Chicago, U.S.A.); concentrations of selected elements (XRF or INAA; H. Palme, G. Weckwerth) in wt%: Al: 14.68; Si: 20.73; Mg: 2.68; Fe: 3.5; Ca: 11.1. Specimen: Type specimen, 20 g and polished thin section, Mün; main mass, anonymous finder.
