Kumtag 056        41°42’3.15"N, 93°43’26.98"E

Xinjiang, China

Find: 2019 Mar

Classification: Ordinary chondrite (L5)

History: (Ziyao Wang) Discovered by Wentao Yang (Urumqi) in the desert near Kumtag (Xinjiang Province) in Mar 2019

Physical characteristics: (Ziyao Wang) Three black stones with a total weight of 1020 g were discovered within 1.5 m distance.

Petrography: (R. Bartoschewitz, Bart) well-defined chondrules (0.3-1.0 mm, av. 0.6 mm) of various types and chondrule fragments are set in recrystallized matrix. Metal and sulfide penetration into cracks blackened the meteorite.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa23.5±0-5 (n=20); pyroxene Fs19.1±0.3Wo1.8±1.1 (n=5); chromite CRAL=86,m FFM=75. Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 4.68

Classification: Ordinary chondrite (L5, W2)

Specimens: 22.6 g on deposit at Kiel, Ziyao Wang holds the main mass, and 101 g with Bart.
