| Summary: | Search for Antarctic meteorites was carried out by the wintering party of the 22nd Japanese Antarctic Research Expedition in the Meteorite Ice Field in the vicinity of the Yamato Mountains in December 1981. Search in the hexagonal experiment area showed that the emergence of meteorites from the ice sheet due to ablation of ice took place at a rate of one meteorite per year per 2(km)^2 during two years. Collected specimens are 133 in number and 25.928kg in weight, and consist of ordinary chondrites, carbonaceous chondrites and diogenites. Distribution of occurrence sites suggests that a bare ice field near small nunataks is the meteorite-concentrated area, as was pointed out before. |
