SEYMCHAN METEORITE — AN EXTRATERRESTRIAL NUMERO 7
Pallasite - PAL
Magadan District, Siberia

While not appearing to be from the same meteorite as the previous lot, this is indeed a partial slice a Seymchan meteorite. Seymchan is a transitional pallasite; as previously described, there are areas with no olivine crystals, areas loaded with crystals and then there are the heterogeneous boundary areas of which this is an example. Punctuated with black silicates, prominent bands of nickel-iron have been polished to a mirror finish. If etched, this specimen would exhibit the coarse octahedral pattern seen in the previous lot. The crystals seen here are olivine (magnesium iron silicate). Like all pallasites, this specimen formed at the mantle-core boundary of a planet between Mars and Jupiter which no longer exists, and whose remnants comprise the asteroid belt. “Number 7” is a fine example of a fascinating meteorite. (For further information on pallastic meteorites see lot 11.) 208 x 219 x 2mm (8.0 x 8.5 x 0.1 inches) and 214 grams (0.5 pounds).

Estimate: $3,500 - 4,500
