Jiddat al Harasis 348
Oman
Find: 6 March 2006
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.
