Writeup from MB 102:

Heyetang        27°14’ 48.73” N, 111°19’ 18.72” E

Hunan, China

Fell: late October 1998

Classification: Ordinary chondrite (L3)

History: In late October, 1998, Mr. Wen and his friends heard a loud shrill sound and saw a fireball and subsequent landing of a meteorite about 200 m away. The meteorite embedded itself in a recently harvested rice field. The stone was said to be hot after being dug from the hole. It was bought by IGGCAS in August, 2012.

Physical characteristics: The 2.5 kg meteorite is an almost complete rounded stone covered by black fusion crust. Small light gray-colored chondrules set in matrix are evident. Rust spots on the surface.

Petrography: (G. Wang GIGCAS. W. Shen and S. Hu, IGGCAS). Chodrules 100-1500 μm in diameter, average ~300 μm. The chondrules/matrix ratio is about 5. The abundance of metal and sulfide is about 5 vol%.

Geochemistry: (G. Wang, X. Jiang and D. Wang, GIGCAS; W. Shen, S. Hu and Y. Lin, IGGCAS). Olivine, Fa6.69-33.5, low Ca-pyroxene, Fs1.70-40.3Wo0.09-5.71. Opaque minerals dominated by sulfide, kamacite, and taenite with minor limonite. The average content of Co is 7.1 mg/g in kamacite.

Classification: Ordinary chondrite, L3, S2, W1.

Specimens: Most of the sample is on deposit at IGGCAS. About 90 g of sample is on deposit at GIGCAS.
