Oman
Found 1999 November 29
Lunar meteorite (feldspathic fragmental breccia)
A brownish gray stone of 174 g covered by fusion crust was found in the Dhofar region of Oman. Classification and description (A.
Greshake, MNB): a feldspathic fragmental breccia consisting of clasts of various lithologies embedded into a devitrified fine-
grained matrix; schlieren and vesicles are abundant; feldspar, An96.5- 99.5; pyroxene, Fs21.9-46.2 Wo3.0-41.4; olivine, Fa29.3-47.8; augites are more abundant than Ca-poor pyroxenes and often contain pigeonite exsolution lamellae; accessory phases are Fe-Ni metal, ilmenite, and Ti-Cr-rich spinel; crystalline fragments include large gabbroic anorthosites, high-Al highland basalts, microporphyritic impact melt breccias, dark fine-grained impact melt breccias, and large
cataclastic feldspar; no regolith components, e.g., glass spherules, have been identified; low bulk concentrations of MgO and FeO reflect low abundance of mafic components. Specimens:19.8 g plus two thin sections, MNB; ~20 g, M¸n; main mass with anonymous finder.
