Fragment of a lunar meteorite fragment. Bechar 003 Lunar feldspar gap 30.887°N, 3.301°W Bechar, Algeria On March 24, 2022, numerous small stones of similar appearance were found together in Algeria. The stones (2090 g in total) lack a fusion crust and have brownish weathered exteriors. The freshly exposed interiors are mid-gray with diffuse small white clasts and rare tiny metallic grains visible. Electron microprobe analyses were performed on small portions from four different stones. Although there is some mineralogical and compositional heterogeneity among these pieces, all consist of mineral clasts of calcium-rich plagioclase, olivine, pyroxene with low calcium content, and water within a matrix of very fine grains that is sparsely microvesicular.
