Repost from @dilute_the_power The Fukang meteorite is a meteorite that was found in the mountains near Fukang, China in 2000. It is a pallasite—a type of stony–iron meteorite with olivine crystals. It is estimated to be 4.5 billion years old. The Fukang pallasite contains large, gem quality olivine, or peridot, in a nickel-iron matrix. Olivines vary in shape from rounded to angular, many are fractured and they range in size from less than five millimetres to several centimetres. The main mass contains several regions of massive olivine clusters up to eleven centimetres (4.3 inches) in diameter with thin metal veins. Fo86.4 with molar Fe-Mg = 0.1367, Fe-Mn = 40.37, and Ni = 0.03 wt%. The metal matrix is mostly kamacite with an average Nickel contents of 6.98 wt%. Vermicular sulfide (troilite) is present in some olivine. Oxygen isotopes: δ18O 2.569 ‰, δ17O 1.179 ‰, ∆1 7O = −0.157 % DiluteThePower @dilutethepower: This is a piece of the Fukang meteorite, a 1,003 kilogram meteorite discovered in China.
