The glacial series refers to a particular sequence of landforms in Central Europe that were formed during the Pleistocene glaciation beneath the ice sheets, along their margins and on their forelands during each glacial advance.〔(''Die glaziale Serie und glaziale Sonderformen in Schleswig-Holstein'' ). Forum Erdkunde, Uni Lünibürg. Accessed on 6 January 2008.〕 == Definition == The term "glacial series" ((ドイツ語:Glaziale Serie)) was used as early as 1882 by Albrecht Penck initially for the northern Alpine Foreland. Later the term was expanded and used to refer to the Scandinavian glaciation region. The elements of an ideal and complete glacial series are:〔 * a ground moraine with a tongue-like basin (''Zungenbecken'') * a terminal moraine chain that lies in an arc around the ''Zungenbecken'' * a gravel field or sandur outwash plain in front of the terminal moraine chain * a glacial meltwater valley (''Urstromtal''), through which meltwaters from the glacier flowed away. The term "glacial series" is restricted to landforms created by glaciers and classified by geomorphological rules, as opposed to the glacial sediments and sedimentary rocks associated with glaciers and classified by their geological features. A complete glacial series is formed when the edge of the ice sheet remains static for a long time and is not destroyed again by a further advance of the ice mass. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glacial series」の詳細全文を読む スポンサード リンク
