Ququkesu 002 37°20.420’ N, 83°3.768’ E Xinjiang, China Find: 2023 Dec 18 Classification: Ordinary chondrite (LL3) History: (Ziyao Wang, WangZ) Discovered by Ashanjiang Mahemuti in the Taklimakan desert, near Minfeng County, Xinjiang, on Dec. 18, 2023. Purchased by Ziyao Wang and donated to R. Bartoschewitz. Physical characteristics: (Ziyao Wang, WangZ) brown flat stone of 28 g with voids of weathered out chondrules. Petrography: (R. Bartoschewitz, Bart) Well-defined chondrules (840±340 µm, n=20) and large fragments (~3 mm) of complex chondrules containing rare devitrified glass are irregularly distributed in a matrix containing metal (partly altered to Fe-oxihydrates), troilite and chromite. Geochemistry: (R. Bartoschewitz, Bart, and P. Appel, Kiel) Olivine Fa11.9±8.4 (n=21; range Fa1.2-23.0); low-Ca pyroxene Fs7.2±5.2Wo0.8±0.7 (range Fs1-22Wo0.3-3.2; n=18); high-Ca pyroxene En84-59Fs1-22Wo5-40 (n=5); glass An75-84Or<1 (n=3); chromite CRAL=50-93, FFM=64-94 (n=5). Kamacite Ni=2.8-8.8, Co=0.7-0.9 (n=2); troilite Ni<0.16 (n=11) (wt%). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 3.30±0.13 (n=4); bulk density 3.13 g/cm³. Classification: Ordinary chondrite (LL3, S1, W3; estimated subtype 3.7 basing on s-Fa and s-Fs. Specimens: 5.6 g on deposit at IfP, main mass with Bart | ||||||||||||||||||||||||||||||||||||||||
