“…Beginning with ALHA (Allan Hills) 81005 in 1982 (Bogard, 1983;Marvin, 1983), ϳ24 lunar meteorites have been identified in the past 20 yr (Table 1). The exact number is not known with certainty because many new ones have been found each year for the past several years and pairing relationships among the newest lunar meteorites have not been established.…”

“…For example, there are some pairs of elements, such as Fe and Mn or Ga and Al, that appear to behave very similarly in most magmatic systems but have different cosmochemical properties (such as volatility), so their ratios tend to be relatively constant among rocks from a single body but differ between bodies. Hence, arguments based on Fe/Mn, GdAI and other chemical systems were crucial in the acceptance of ALH 8 1005 as the first lunar meteorite (at least six papers in a special collection (Bogard, 1983) refer to Fe/Mn ratios in either the abstract or figures) and of ALH 84001 as a martian meteorite (Mittlefehldt, 1994). Brachina and ALH 84025 have much higher ratios of Fe to Mn than martian, lunar, terrestrial or HED meteorites, which has led to the conclusion that they are distinct from any of these better-known groups but share a common parent body (Warren and Kallemeyn, 1989).…”

Abstract-Eagles Nest and Lewis Cliff (LEW) 88763 are olivine-rich achondrites that have been suggested to be related to Brachina and ALH 84025. Both are ultramafic, although LEW 88763 has -10% plagioclase, which Eagles Nest lacks. Olivine in Eagles Nest (Fo68) is virtually identical in composition to that in Brachina (F068-70), and that in LEW 88763 is only slightly different (F063-64). The meteorites' cosmic-ray exposure ages differ from each other and from Brachina and ALH 84025. Like Brachina, Eagles Nest has a substantial amount of radiogenic 129Xe and an apparent K-Ar age of ~4 . 5Ga. Lewis Cliff 88763, on the other hand, has no detectable radiogenic 129Xe, an apparent K-Ar age of -4.5 Ga, and a substantial amount of trapped Xe. The chemical composition of LEW 88763 is within a factor of two of chondritic for virtually every element analyzed, including siderophiles, which suggests that it was melted (or at least heated and recrystallized) in a closed system. Analyses of the chemical composition of Eagles Nest are hampered by extensive terrestrial weathering; but it appears to be broadly chondritic also, although it, like Brachina, is depleted in siderophiles. Our data suggest that Eagles Nest is genetically related to Brachina but that LEW 88763 is not, which is a conclusion that is consistent with the 0 isotopic data of Clayton and Mayeda (1 996).

“…With the discovery and identification of the first lunar meteorite in 1983 (Bogard ), lunar meteorites have provided additional samples to continue investigating the origin and evolution of the Moon. Apollo samples are invaluable for their petrologic data combined with known sampling locations; however, lunar meteorites offer the ability to randomly sample the surface of the Moon, potentially including the farside, although the exact source locations for the meteorites are unknown.…”

Northwest Africa (NWA) 10986 is a new mingled lunar meteorite found in 2015 in Western Sahara. This impact melt breccia contains abundant impact melt glass and clasts as large as 0.75 mm. Clasts are predominantly plagioclase and pyroxene‐rich and represent both highland and basalt lithologies. Highland lithologies include troctolites, gabbronorites, anorthositic norites, and troctolitic anorthosites. Basalt lithologies include crystalline clasts with large zoned pyroxenes representing very low titanium to low titanium basalts. In situ geochemical analysis of minerals within clasts indicates that they represent ferroan anorthosite, Mg‐suite, and gabbronorite lithologies as defined by the Apollo sample collection. Clasts representing magnesian anorthosite, or “gap” lithologies, are prevalent in this meteorite. Whole rock and in situ impact glass measurements indicate low incompatible trace element concentrations. Basalt clasts also have low incompatible trace element concentrations and lack evolved KREEP mineralogy although pyroxferroite grains are present. The juxtaposition of evolved, basaltic clasts without KREEP signatures and highland lithologies suggests that these basaltic clasts may represent cryptomare. The lithologies found in NWA 10986 offer a unique and possibly a complete cross section view of the Moon sourced outside of the Procellarum KREEP Terrane.
