Also Neo-.
[f. neo- + glaciation.]
A minor, short-lived increase in glaciation following the major glacial retreat at the end of the Ice Age.
Though freq. attributed to F. E. Matthes, the term appears not to have been used by him in print.
1951J. H. Moss Early Man in Eden Valley v. 62 In the Sierra Nevada, Matthes (1939) has described a similar set of small, very fresh moraines fronting the existing glaciers... They contrast sharply with the older moraines slightly farther down the valley. Matthes suggested the name Neo-glaciation for the minor glacial pulsation represented by these moraines, and pointed out that it probably postdates the so-called Climatic Optimum. 1954Jrnl. Geol. LIV. 340/1 Most of the moraines described in the literature which have been correlated with the Neoglaciation are close to, or in contact with, existing ice masses and are devoid of all vegetation. 1970Sci. Amer. June 102 Historical records of the latest glacier fluctuations during neoglaciation are available from many alpine regions. |
