CORRELATION OF 



Scandinavian 



J. Geikie, 1894-19U 

 IV Glaciation = Mecklenburgian 



Relatively restrained, local gla- 

 ciers in the British Isles, in the 

 diverging valleys of the High- 

 lands and the Grampians; 

 large terminal moraines in 

 Denmark, Schleswig - Holstein, 

 northern provinces of Ger- 

 many, and Russia. Glaciers 

 of Scotland and Norway not 

 joined. [Several moraines of 

 north Germany that are in- 

 cluded by German geologists 

 in the last glaciation are out- 

 side the limits of Geikie' s 

 Mecklenburgian. — Leverett. ] 



III Glaciation = Polonian 



Less extensive than Glaciation 

 II ; northern Britain beyond 

 the midlands shrouded in ice. 

 [These British moraines ap- 

 pear to be the correlatives of 

 the outer moraines of the last 

 glaciation in north Germany. 

 They appear to be younger 

 than the "Middle Drift" of 

 north Germany and also 

 younger than the Riss drift of 

 the Alps. The "Middle Drift" 

 and Riss drift appear to be 

 correlatives. — Leverett.] 



II Glaciation = Saxonian 



The most extensive; in England 

 united glaciers of Scandinavia 

 and Scottish Highlands ex- 

 tending southward to the 

 Thames, depositing there the 

 "Old Drift" or "lower Boulder- 

 clay" ; in Germany extending 

 to the foot of the Harz Moun- 

 tains, Bohemia, and Saxony, 

 spreading eastward over the 

 Russian plain to Moscow, and 

 joining the Ural glaciers. 

 "Old," or Saxonian, drift, the 

 most external ground moraine. 



I Glaciation = Scanian 



The least extensive ; along the 

 basin of the Baltic Sea, spread- 

 ing only to Scania and the Ger- 

 man plain through Hamburg 

 and Berlin ; not reaching the 

 British Isles. [Wahnschaffe 

 (1909.1) and Leverett (1910.1) 

 find the equivalent of the Giin- 

 zian in well borings near Ber- 

 lin and near Hamburg, Ger- 

 many. Gagel (1913.1) finds no 

 equivalent of the Giinzian on 

 the German plain.]
