Al Qou’a 002        23°15’40.2"N, 55°16’11.8"E

Abu Zaby, United Arab Emirates

Find: 2014 Oct

Classification: Ordinary chondrite (L3)

History: (D. Heinlein) The stone was found above the surface of the red sands in a dune region south of Al Qou’a town.

Physical characteristics: (D. Heinlein) The mass of the stone block is 22.4 kg, the dimensions are 37 × 35 × 19 cm. The magnetic susceptibility MS was determined to log χ (× 10-9 m3/kg) = 4.52±0.12.

Petrography: (F. Langenhorst, UJena) Unequilibrated ordinary chondrite, consisting of chondrules and chondrule fragments (chemical types I and II), Fe-Ni metal and abundant troilite, as well as interchondrule matrix. The apparent chondrule size is 580 µm (210-2100 µm range)

Geochemistry: (F. Langenhorst, J. Langbein, UJena) Mineral compositions and geochemistry: The mean olivine composition is Fa22.4±6.7 (Fa6.2-30.5; n=18); the mean low-Ca pyroxene composition is Fs20.4±9.7Wo2.1±1.3 (Fs5.9-44.5Wo0.4-3.9; n=13).

Classification: (F. Langenhorst, UJena) L chondrite, based on mean apparent chondrule size and metal content. Petrologic type 3 (proposed subtype 3.6), based on the chemical variation of olivine and the presence of secondary albite in chondrules

Specimens: Type Specimen: 20 g, UJena; 26.2 g, Heinlein; the main mass is with the finder.
