In order to clarify the stable isotope characteristics of the ground ice bodies such as polygons, ice wedges, pingos and massive ices in the permafrost, the oxygen isotopic composition was determined for ground ice samples collected at Barrow, Alaska and Tuktoyaktuk, Mackenzie Delta, North Canada, and was discussed with special references to the formation process and the origin of water of these ground ice bodies.<BR>The ground ice bodies showed their characteristic oxygen isotopic compositions originated from their formation process and origin of water. Of course, even in the same kind of ground ice bodies, each ice body showed different oxygen isotopic compositions, which are due to the difference of the water body. It was indicated that the stable isotope characteristics of the ground ice bodies may regionally differ. The formation process as well as the origin of water may regionally differ even among the same kind of ground ice bodies.<BR>A thought presented in this study for the stable isotope fractionation accompanied by the movement of water during frost heaving was confirmed with the actual findings.
