Kumtag 003        41°30’N, 93°33’E

Xinjiang, China

Found: November 2011

Classification: Ordinary chondrite (H5)

History: In November, 2011, a meteorite was found in the Tuzileike Desert when a geologist, Jianmin Wang, was working in the geological survey. Since then on, Mr. Wang and his colleagues have been searched for meteorites in an ~60 km2 region. In 2012 other hunters have also searched for meteorites, finding more than 270 kg.

Physical characteristics: (S. Hu, IGGCAS): 120 g irregular shaped (5 × 4 × 3 cm) rock lacking fusion crust.

Petrography: (S. Hu, IGGCAS): Recognizable chondrule types include porphyritic and barred olivine/pyroxene. Matrix recrystallized. Metal and troilite are relatively fresh, sometimes with thin weathering rims.

Geochemistry: Olivine Fa19.2±0.9, n=5; low-Ca pyroxene Fs16.7±0.6, n=5.

Classification: Ordinary chondrite (H5), S2, W1.
