Jiddat al Harasis 348 (JaH 348)

Oman
Find: 6 March 2006
Mass: 18.4 g (1 piece)

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 compositions: 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, An96.5.

Classification: Lunar (feldspathic fragmental breccia).

Type specimens: A total of 3.7 g is on deposit at NAU. Robert Ward holds the main mass.

Randy Says…

JaH 348 is similar in composition and appearance to paired stones Dhofar 1436 and Dhofar 1443 collected 143 km away. The two meteorites might be launch paired. Or, maybe not. It’s a feldspathic lunar meteorite of anorthositic norite composition.
