Jiddat al Harasis 348 (JaH 348)
Classification: Lunar (feldspathic fragmental breccia)
History and physical characteristics: A small (18.4 g), complete stone with no remaining fusion crust was recovered from the Jiddat al Harasis region of Oman on March 6, 2006, by Robert Ward.
Petrography: (J. Wittke and T. Bunch, NAU): Clast-rich, fragmental breccia with sparse vesicles (<0.3 mm) that is dominated by many varieties of quench-textured impact-melt breccias and plagioclase fragments. Minor amounts of anorthositic olivine gabbros, troctolites, and olivine/pyroxene fragments are also present.
Mineral Composition: Anorthositic gabbro olivine (Fa28.4–32.2, FeO/MnO = 89 to 98; Ca-rich pyroxenes, Fs10.1–25.7Wo40.6–13.0; plagioclase, An95.2–97.7), troctolite olivine (Fa17–24.3, FeO/ MnO = 96 – 103), plagioclase, An96.
Classification: Lunar (feldspathic fragmental breccia).
Specimens: A total of 3.7 g is on deposit at NAU. Robert Ward holds the main mass.
JaH 348 is similar in composition and appearance to paired stones Dhofar 1436/1443 collected 143 km away. The two meteorites might be launch paired. Or, maybe not. It is a feldspathic lunar meteorite of anorthositic norite composition.
