事实告诉我们除非你发现的是目击陨石和火星月球等珍稀陨石才会有人关注你，掏真金白银给你买，其他的发现陨石根本就没人会搭理你，为你买单，普通发现陨石实在太多太多了，天文馆所收藏的南极陨石还堆在仓库里大部分都还没时间研究，陨石藏家手里的普通发现陨石也是成吨的堆着愁出手，你民间发现的那几块破石头哪有闲心搭理你，更何况很难遇到几块真的，几块真的也是普品，还受地球环境污染严重，根本就没多少价值
确实已经获得国际命名 Tongan
Tongan 24°32’21"N, 110°59’6"E
Guangxi, China
Found: 1996
Classification: Iron meteorite (IAB-MG)
History: A large iron meteorite was found by a farmer in his field in Miaobei village, Zhongshan County, in 1996, and then purchased by Mr. Yongxing Liang, a retired official in Zhongshan county, Guangxi Province, in 2001. The find site is near the boundary with Zhongshan county.
Physical characteristics: This meteorite was not weighed accurately and is estimated to be about 500 kg. It is dark brown in color due to a thin layer of limonite and has an angular shape without any fusion crust. Surface covered with abundant centimeter-sized cavities.
Petrography: (B. Miao, H. Chen, Z. Xia, L. Xie, GUT; Y. Lin, IGGCAS): The meteorite is dominated by kamacite with a bandwidth of 10.5 mm on average. Taenite occurs as thin lamellae 30-100 μm wide. Kamacite (5.59-7.59 wt% Ni; 0.96-1.29 wt% Co) and taenite (17.9-34.0 wt% Ni; 0.33-0.88 wt% Co).
Geochemistry: (K.V. Ponganis, UCSD; B. Spettel, MPI) Bulk composition (by INAA): Fe 91.9%, Ni 6.60%, Co 4330 mg/g, Ga 88.6 μg/g, Ge 301 μg/g, As 11.9 μg/g, Mo 8.20 μg/g, Ir 2.34 μg/g.
Classification: Iron (IAB-MG)
Specimens: 150 g of the sample is on deposit at GUT and 200 g at IGGCAS.
