内容記述 |
Debris-laden basal ice is exposed along an ice cliff (about 30m high) near Hamna Icefall, Soya Coast, East Antarctica. The basal ice about 6.8m thick can be divided into an upper part (5.5m) and a lower part (1.3m) based on stratigraphic features. Major dissolved ions of the basal ice are probably composed of eight species (Na^+, K^+, Mg^<2+>, Ca^<2+>, Cl, SO_4^2,NO_3 and HCO_3). Almost all Na^+, K^+, Mg^<2+>, Ca^<2+>, SO_4^2 and HCO_3 in the basal ice are considered to have originated from chemical erosion of rock minerals at the base of the ice sheet. According to a calculation of ion composition, the primary rock mineral dissolved in the basal ice is considered to be carbonate. |
