Writeup from MB 109:

Wubao 002 42°17’47.80"N, 92°28’18.93"E

Xinjiang, China

Find: 2018

Classification: Ordinary chondrite (LL3)

History: (Ziyao Wang) Discovered by Wentao Yang (Urumqi) in the desert near Dahaidao (Xinjiang Province) in 2018

Physical characteristics: (Ziyao Wang) Gray-brown stone of 105 g without fusion crust

Petrography: (R. Bartoschewitz, Bart) well defined chondrules (~50 vol%) of 0.3-2 mm (av. 0.7 mm) and AOIs (~10 vo%) are set in a black opaque matrix with few irregular metal and sulfide aggregates up to 0.3 mm (<1 vol%).

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa_14.1±7.7(n=31) (range Fa_0.6-31.4), Fe/Mn=43, Fe/Mg=0.17; low Ca pyroxene Fs_8.7±5.7Wo_0.7±0.7(Fs_1.5-15.6Wo_0.2-2.2, n=8); pigeonite En₇₇Fs₁₈Wo₅(n=1); feldspar An₈₅Ab₁₅(n=1). Kamacite Ni=2.6-5.1, Co=0.4-0.9 wt% (n=8). O-isotopes (A. Pack, UGött): δ¹⁷O(‰) = 4.151, δ¹⁸O(‰) = 5.928. Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10^-9 m³/kg) = 4.82 plots outside the LL range, as O-isotopes reflect.

Classification: Ordinary chondrite (LL3, S4, W0-1)

Specimens: 17.8 g at Kiel and 4.7 g at UGött on deposit, Ziyao Wang holds the main mass and 27 g with Bart.
