英文摘要	The paper describes the pioneering study of morphology and structure of frost mounds on Bely Island in the Kara Sea. Age of peat, carbon isotopic composition of peat and gas inclusions in ice, ice crystalline structure, and granulometric composition of sediments have been determined. By their shape, the identifi ed frost mounds have been grouped into conical, toroidal, thaw-weakened (without ice core) frost mounds crosscut by polygonal network, and ice-cored fl at-topped perennial palsas. Modern palsas are distributed in the areas of laida which are regularly fl ooded by sea water. Conical and toroidal frost mounds represent relict permafrost landforms developed in the late Holocene. Relict frost mounds of Western Yamal and Arctic islands can be indicators of coastal-marine settings of their growth on low elevations in the late Holocene.
