内容記述 | The huge depression of the central part of Lutzow-Holm Bay is the drowned glacial trough extending from the Shirase Glacier. This trough and another off the Telen Glacier were formed probably by glaciation along faults. The sea floor of Lutzow-Holm Bay is divided into the eastern and the western parts by the central trought. The greater part of the western sea floor is 300m deeper than the northeastern sea floor. This difference in depth was caused probably by faulting. Many drowned glacial troughs exist in the eastern part. They were eroded selectively by ice streams conformably with the strike of gneissic foliation of bedrock. Rows of circular depressions seem to have been formed also along the strike of foliation by the plucking of the ice sheet. Cross profiles of troughs indicate the possibility of occurrence of multiple glaciations. Directions of troughs are different from those of glacial striae in coastal ice-free areas, and this seems to indicate that part of lower ice in troughs flowed in the different direction from the upper part of the ice sheet. | |||||||||
