A TRANSITIONAL SLICE OF SEYMCHAN METEORITE
Pallasite – PMG
Magadan District, Russia (62°54’ N, 152°26’ E)
A highly aesthetic long thin Seymchan transitional pallasite slice and a notable example of the textural heterogeneity of the Seymchan meteorite. The metal-rich areas display a prominent Widmanstätten pattern and represent the olivine-free region at the top of the iron-nickel core. The olivine-rich aggregates were derived from a fragmented olivine layer at the bottom of the mantle that was invaded by a metallic liquid during mixing at the core-mantle boundary; supported on fitted stand
10½ x 3in. (272 x 65mm.)
