panplanation Physical Geogr.|ˌpænplæˈneɪʃən|
[f. pan- + planation, after panplain.]
The formation of a panplain.
1933C. H. Crickmay in Geol. Mag. LXX. 345 The essential difference between panplanation and peneplanation is that the former starts from the lower floodplains of rivers and grows laterally in all landward directions, whereas the latter is of universal occurrence. 1942O. D. von Engeln Geomorphol. xvi. 356 It is now considered improbable that flood-plain accumulation and panplanation (Crickmay, C.H., 1933) combined..could completely dispose of all relief in a peneplaned region. 1970R. J. Small Study of Landforms v. 168 Many authorities have regarded lateral plantation by running water as a major factor in the formation of desert surfaces.., and a process akin to panplanation has been assumed by some to account for savanna plains. |
