History: On 2008 April 12, about 4 pm, people were chatting in Xinglongquan village, Dong Ling township, Zun Hua city, when they heard a loud explosion from Wang Shulan’s house. Inside the house, they smelled something like gunpowder. Two main stones and some other pieces were scattered on the floor and there was a hole on the roof. After 2 days, Lei Kesi went to the villager’s house, a bought the meteorite. A Chinese website reported the incident.
Physical characteristics: Total mass: more than 2000 g (two main pieces about 900 and 700 g and several small pieces) gray-white inside with fresh black fusion crust.
Petrography: Recognizable chondrules constitute up to 51.2 vol%. The fragments of chondrules and minerals comprise 19.1 vol%. Fe-Ni metal grains constitute ~4.4 vol%, sulfide 1.9 vol%, and matrix 23.4 vol%. Chondrule boundaries are very clear, and discrete plagioclase crystals are not visible in devitrified mesostasis of barred olivine chondrules. The chondrules’ long axes are 0.2 to 2.1 mm, average 0.68 mm. The short axis is 0.1 to 1.6 mm, average 0.49 mm. On the polished thin section, there are two clasts 4.1 × 2.6 mm and 4.5 × 2.3 mm in size; the matrices range from opaque to subtransparent. Fe-Ni metal grains constitute to about 4.4v ol%, the sulfide 1.9 vol%.
Geochemistry: The mineral compositions are very heterogeneous, olivine Fa19.2±7.85, N=32, pyroxene Fs15.2±8.3, N=47. Co content of kamacite is 18.1 mg/g.
Classification: Ordinary chondrite L3; S1; W2.
Specimens: More than 20 g sample and two thin section are deposited at GUT.
