Jiddat al Harasis 1118 (JaH 1118)
Al Wusta, Oman
Lunar meteorite (feldspathic breccia)
History: The meteorite was found during a field trip in the Jiddat al Hararsis dense colection area.
Physical Characteristics: Dark grayish rock lacking fusion crust.
Petrography: The meteorite is a feldspathic breccia composed of up to 2 mm sized lithic (gabbroic and melt rock) and mineral clasts set in a fine-grained clastic mineral matrix. Dominant minerals are anorthite, zoned pyroxene, pigeonite, and olivine. Minor phases include ilmenite, chromite, and troilite.
Geochemistry: (A. Greshake, MNB ) olivine: Fa22.6±0.2 (Fa22.4-23.0), FeO/MnO=91±6 (n=7); ferroan olivine: Fa41.0±0.3 (Fa40.5-41.5), FeO/MnO=84±4 )n=7); zoned pyroxene: Fs42.5±17.4 Wo25.3±4.4 (Fs20.4-68.1Wo20.2-32.6, FeO/MnO=55±8 (n=7); pigeonite: Fs35.3±0.3Wo6.1±0.2 (Fs35.1-35.6Wo5.8-6.4), FeO/MnO=53±3 (n=7); calcic plagioclase: An95.6±2.4 (An<90.1-97.1, n=7).
Classification: Lunar Meteorite (feldspathic breccia)
Specimens: 21 g at MNB, main mass with anonymous finder.
I have not studied JaH 1118. It was found 136 km northeast of JaH 838 and 106 km northeast of JaH 348
