Seymchan Pallasite Meteorite Etched Block. The Seymchan meteorite first discovered in eastern Russia in 1967 is one of the most unusual scarce Palasites known. The first two large meteorites found were cut and polished showing only an iron-nickel matrix. Finally, after most of one of the meteorites was cut, there appeared olivine crystals which makes this meteorite a rarer Pallasite. It is an unusual Pallasite because the olivine crystals are only found in a small portion of the meteorite and not evenly difivided throughout. This sizeable block of Seymchan is 65 x 60 x 11mm weighing 289.4 grams and is etched on both sides to show it Widmanstatten pattern as well as two concentrated sections with olivine crystals measuring 42 x 20 mm on one side and 35 mm long on the opposite side. The Widmanstatten pattern is also quite unusual in that it is not uniform and is distorted from intense heat and shock when it was formed from a massive collision of two large asteroids in the asteroid belt many millions of years ago.
