Writeup from MB 109:

Baqiangzi        43°54’09.2"N, 93°12’13.2"E

Xinjiang, China

Find: 2012

Classification: Enstatite chondrite (EL7)

History: (Ziyao Wang) One piece was discovered by the geologist Jianming Wang (Hami/Xinjiang) during field work near Barkol in 2012. After confirmation of its meteoritic nature, Jianming Wang discovered further fragments in 2019.

Physical characteristics: (Ziyao Wang) Three dark-yellowish, irregular stones of 899, 176 and 125 g.

Petrography: (R. Bartoschewitz) Breccia of dark olive-green silicate clasts with fine metal particles in a lighter host, often separated by a spongy network of metal veins. Strongly recrystallized meteorite (av. grain size ~100 µm), with few chondrules relict up to 0.8 mm. Main minerals are olivine, pyroxene, metal, and sulfides. Feldspar grains are up to 150 µm.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) olivine Fa0.2±0.1 (n=19); low-Ca pyroxene Fs0.3±0.1Wo1.4±0.3 (n=6); diopside En53Fs1Wo46 (n=2); feldspar An17±5Or2 (n=3). Kamacite Ni=6.9, Co=0.7, Si<0.1 (n=6); troilite Cr=0.7, Ti=0.2 (n=4); alabandite Fe=6 (n=1) (all wt-%). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 5.45

Classification: Enstatite chondrite (EL7, W1), based on texture and plagioclase size

Specimens: 20.4 g on deposit at Kiel, Ziyao Wang holds the main mass, and 17 g with Bart.
