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 Fa14.1±7.7 (n=31) (range Fa0.6-31.4), Fe/Mn=43, Fe/Mg=0.17; low Ca pyroxene Fs8.7±5.7Wo0.7±0.7 (Fs1.5-15.6Wo0.2-2.2, 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. | ||||||||||||||||||||||||||||||||||||||||
