摘要 请点击此处下载与本文相关的地图。展示了俄罗斯西北部摩尔曼斯克地区科拉半岛和邻近地区的冰川地貌图。地貌识别和分类的主要数据来源是 Landsat 7 增强型专题制图仪 Plus (ETM+) 卫星图像以及选定区域的航空照片解释和实地工作。该地图比例尺为 1:900,000，包含 20,000 多个与第四纪冰川活动有关的地貌，极大地丰富了该地区的现有知识。已绘制地图的地貌类型有冰川线纹、肋状冰碛、末碛、末碛复合体、丘状冰碛、埃斯克、冰川堆积、侧向融水通道、大型融水通道、超大融水通道和残余海岸线。地貌分布变化较大。除了丰富的横向融水通道外，半岛的中部缺乏冰川活动的迹象。在该地区的其余地区，冰川线（鼓状线、尤特线、岩尾线）是主要的地貌类型。该地区最大的冰川地貌系统是平行于科拉半岛南部和东部海岸的冰缘系统。这个冰缘系统，即凯瓦冰碛复合体，部分已被来自西南方向的冰流淹没并形成鼓状。这表明该冰边缘带是在最后一次大规模冰扩张之前沉积的。所提供的地图将用作芬诺斯坎迪亚冰盖地区东部冰川事件新重建的主要数据来源。

A map of the glacial geomorphology of Kola Peninsula and adjacent areas in the Murmansk region, northwestern Russia, is presented. The primary data source for identification and classification of landforms has been Landsat 7 Enhanced Thematic Mapper Plus (ETM+) satellite images, and aerial photograph interpretation and field work in selected areas. The map, at the scale 1:900,000, consists of over 20,000 landforms pertaining to the Quaternary glacial activity, considerably improving existing knowledge of this area. The landform types that have been mapped are glacial lineations, ribbed moraine, end moraines, end moraine complexes, hummocky moraine, eskers, glaciouvial accumulations, lateral meltwater channels, large meltwater channels, very large meltwater channels, and relict shorelines. The distribution of landforms shows large variations. The central part of the peninsula lacks signs of glacial activity, apart from abundant lateral meltwater channels. In the rest of the area glacial lineations (drumlins, utes, crag-and-tails) are the dominant landform type. The largest glacial landform system in the area is an ice marginal system running parallel to the southern and eastern coast of Kola Peninsula. This ice marginal system, the Keiva moraine complex, has in part been overrun and drumlinised by ice ow from the southwest. This indicates that this ice marginal belt was deposited before the last major ice expansion. The map presented will be used as the main source of data for a new reconstruction of glacial events in the eastern part of the Fennoscandian ice sheet area.
