文摘
Interesting structural features of two iron meteorites (Aliskerovo and Bilibino) are described. An observed recrystallization at low temperature (<0,15 of melting temperature) is considered to be induced by water-rock interaction on Earth. An idea of diffusion-induced grain boundary migration is used for explanation of recrystallization mechanism.
