» Meteorite: AL HAGGOUNIA 004» Meteoritical Bulletin Database
Classification: Chondrite CK3 S-medium/W-high
Time/Place: 15 Jan 2015 in Saguia el Hamra, Western Sahara
Mass: 682 gram

History: Four brownish fragments were found by Mr. Zaid Balli at Ouad Ouinaght and subsequently purchased by Marcin Cimala.
Physical characteristics: The meteorite shows a strongly altered brownish-orange sawn surface.
Petrography: The meteorite is composed of separated and clearly defined chondrules set into abundant olivine-rich matrix. Few chondrules contain compositionally unequilibrated olivine and less abundant low-Ca pyroxene. Throughout the matrix olivine is equilibrated. Cr-bearing magnetite and intermediate plagioclase are abundant in the matrix; accessories include Ca-pyroxene, pyrrhotite and troilite.
Geochemistry: Equilibrated matrix olivine: Fa29.4±0.3, n=16; unequilibrated olivine: Fa12.8±10.2 (Fa2.2-29.1, n=15); low-Ca pyroxene: Fs23.0±1.6Wo0.6±0.1 (Fs21.1-24.7Wo0.4-0.8, n=6); Ca-pyroxene: Fs18.3Wo49.2 (N=2); C2O3 in magnetite: 3.8 wt% (N=4)

"The dark inclusion is a CK6 fragment. It is composed of olivine (Fa30.7), augite and feldspar - all recrystallized and chemically equilibrated" by Ansgar Greshake
