» Meteorite: NWA 5205

Northwest Africa 5205
Algeria
Find: 2007
Classification: Chondrite LL3.2

History and physical characteristics:
Several dark brown stones with little remnant fusion crust were purchased in Erfoud in October 2007. TKW is ~ 4 kg.
Petrography (J. Wittke and T. Bunch, NAU):
Polymict breccia with a wide range in chondrule size (0.3 to 11.1 mm). Several igneous-textured, non-chondritic enstatite objects (2 – 7.5 mm) are also present. A few very unusual FeS – Fe oxide- bearing veins (< one mm thick and > 2.8 cm in length) transcend a 6.5x2.6 cm slice. Chondrule mesostasis is nearly free of devitrification. Olivine in type II chondrules is strongly zoned. Weathering grade is W3 and the shock level is S2/3.
Mineral compositions:
Type II PO olivine is Fa7.4 to 38.7, Cr2O3 = 0.07 to 0.48, peak at 0.28 wt %; FeO/MnO = 42 – 54. Enstatite in non-chondritic objects is Fs0.02Wo1.0.
