Study of the Extraterrestrial Materials in Antarctica (VI) : Cosmic Dust Collected from the Glacier Ice of the Meteorite Ice Field, Yamato Mountains
Black spherical microparticles, glassy microparticles and other irregular-shaped particles were collected from the glacier ice, sampled in December 1974, of the Meteorite Ice Field, Yamato Mountains. Their chemical and physical properties were compared with those of previously collected cosmic dust...
