Dar al Gani 1042 27°10.92′N, 16°18.01′E Dar al Gani region, Al Jufrah, Libya Find: 1999 Achondrite (lunar, feldspathic regolith breccia) History and physical characteristics: A single stone
of 801 g with partial fusion crust was found in 1999. Petrography and mineral compositions: (T. Arai, NIPR) Feldspathic regolith breccia with typical lunar highland breccia clasts (e.g., feldspathic crystalline melt breccias, granulitic lithologies, cataclastic anorthosites, etc.) embedded in a well-lithified matrix. Granulitic clasts consist of dominant plagioclase (An95.4–96.7) with orthopyroxene (Wo3Fs19En78, Fe# = 0.19), clinopyroxene (Wo8–12Fs26–28 En62–64, Fe# = 0.28–0.30; Wo44Fs9En47, Fe# = 0.15–0.16), olivine (Fo65–69,81–84), ilmenite, and Ti-rich chromite (Chr45Hc19Usp36). Isolated mineral fragments are plagioclase, co-existing augite and pigeonite, and olivine with ranges of compositions similar to those in the above clasts. Anorthositic impact glasses occur both as glass veins and spherules. The FeO/MnO value of olivines (90 ± 20) supports a lunar origin. Terrestrial calcites pervasively occur along cracks. Classification: Achondrite (lunar feldspathic regolith breccia); moderate weathering. Type specimen: One specimen of 37 g is on deposit at JAXA. One 6.1 g sample and thin sections are on deposit at NIPR. An anonymous finder holds the main mass. | ||||||||||||||||||||
