A difference in the size of Neoglacial lateral moraines on either side of a valley axis (within-valley asymmetry of lateral moraine development) is described. Analysis of clast roundness has revealed subangular material in latero-terminal and terminal moraines; lateral moraines, however, exhibit ...
as it moves, and because of the periodic melting of the ice, which causes the glacier to deposit these materials during warmer intervals. ♦ A moraine that forms in front of a glacier is aterminal moraine. ♦ A moraine that forms along the side of a glacier is alateral moraine. ...
GENESIS OF LAYERED LATERAL MORAINES 来自 ResearchGate 喜欢 0 阅读量: 60 作者: O. Humlum 摘要: Holocene glacier records from the western European Alps are still sparse, although a number of sites are well suited to constraining pre-and early-Little Ice Age (LIA) glacier advances. The ...
quantitative models for their formation: (i) differential erosion rates related to lateral variations in the stream velocity and (ii) lateral incursion from inter-stream ridges after the thinner stream retreats, where the shear margin moraine is consequently just a terminal moraine of the inter-...
