Shişr 162

Zufar, Oman
Found: 17 Feb 2006
Mass: 5525 g

Lunar meteorite (feldspathic breccia)


History: One stone was discovered on a gravel plateau of Miocene limestone of Middle Fars group about 40 km NNE of Shişr.

Physical characteristics: Dark brown stone of 5525 g without fusion crust. Magnetic susceptibility log χ (×10-9 m3/kg) = 2.45.

Petrography: (R. Bartoschewitz, Bart.; P. Appel, B. Mader, Kiel) Breccia of dominantly anorthositic rocks and mineral fragments set in a fine-grained recrystallized matrix of anorthositic composition. Accessory minerals are Ni-rich iron, troilite, and chromite.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Fa17.8-26.4 (mg#(ol) = 73-81), FeO/MnO = 68.2; Fs16Wo15 (mg#(px) = 71-78); FeO/MnO = 50.4; An91.7-97.5; metal Ni 65-125 mg/g, Co 6-10 mg/g. Bulk composition (R. Korotev, WUSL): FeO 3.3 wt%, Sc 5.3 ppm, Sm 0.55 ppm, Th 0.16 ppm, Ni 180 ppm.

Classification: (R. Bartoschewitz, Bart.; R. Korotev, WUSL) Lunar feldspathic impact melt breccia

Specimens: A total of 20.0 g of sample is on deposit at Kiel. 10 g and 2 thin sections are on deposit at Bart, main mass anonymous.


Randy Says…

At 5.5 kg, it's big!
