抄録

Snow-ice cores obtained from ice sheets and glaciers are formed from deposited snow and other materials of marine, terrestrial, cosmic and artificial origin.<BR>The depositional mode of these materials is presumed to be a good signal of climatic and environmental changes during the past several hundred thousand years.<BR>In this report, formation processes of these deposits are investigated mainly on the basis of knowledge of regional characteristics of deposition processes obtained from a comprehensive Japanese glaciological study during 19671989 on the Antarctic Ice Sheet.
