Find: 1992

Classification: Pallasite

History: Approximately 30 years ago (i.e., ~1990), one farmer, in Wulong Village, ArongQi City, Inner Mongolia, China, went to a field seeking building bricks to construct a fence at his residence. He spotted an irregular yellow stone in a farmland and brought it back to his home. The stone was eventually abandoned in his yard due to its shape and weight. Recently, the finder uploaded the picture of stone to the Internet and contacted a Chinese meteorite collector (Ma Rongwei). On Feb. 28, 2022, Ma Rongwei traveled to ArongQi and purchased this stone.

Physical characteristics: The stone weighs about 70 kilograms with an irregular shape in a size of 42 × 38 × 45 cm. The stone looks brownish with a rusty appearance. Numerous large brown to greenish silicate crystals (up to 2 cm) are visible on its exterior.

Petrography: Slices of the stone show a mixture of olivine and metal, with an average of 80% olivine (volume). Olivine grains are dominantly round with a size up to 3 cm, green to brown. Finer-grained irregular olivines occur in patches in some areas of the section. Minor phases include troilite, schreibersite, and chromite.

Geochemistry: Olivine: Fa=12.4±1.2, n=13. Kamacite Ni=6.5±1.1wt%

Classification: Pallasite, based on olivine composition and texture.
