The Morasko meteorite is a coarse-grained metallic octahedrite with many polymineral nodules, belonging according to Buchwald (1975) to group IAB (based on the assumption of a cooling rate of 1.8[degrees]C per million years, on the average germanium content of 40 ppm, and on the established value of the impact pressure of 130-750 kb).
Although I've raved on and on about prolific China, it's only coincidental, really, that this next item also comes from there: it is a meteorite, and a very odd sort of meteorite at that, labeled "octahedrite," from a fall in 1516 A.D.
