摘要:
ABSTRACTIce-cored mounds in a small area in northernmost Sweden are briefly described. The morphological features include hummocks, interpreted as pingos, more palsa-like mounds and fossil forms in the shape of circular ponds. Drilling in one hummock revealed a massive ice core covered by fine grained sediment and glacial till. The sediment is slightly organic and probably of interglacial age. A number of mounds appear to have subsided during the last two decades and no signs of growth have been observed during the same period. The subsidence is assumed to be climatically induced.
