Dirt layers and atmospheric transportation of volcanic glass in the bare ice areas near the Yamato Mountains in Queen Maud Land and the Allan Hills in Victoria Land, Antarctica
Dirt layers containing volcanic ash fragments were found on the bare ice surface in the Meteorite Ice Field near the Yamato Mountains, Queen Maud Land, and near the Allan Hills, Victoria Land. The grain size analysis of volcanic ash fragments shows that the mean grain size in the Allan Hills region...
