Source and origin of Roxana silt and Middle Wisconsinan midcontinent glacial activity / W. Hilton Johnson, Leon R. Follmer.
Title: | Source and origin of Roxana silt and Middle Wisconsinan midcontinent glacial activity / W. Hilton Johnson, Leon R. Follmer. |
Author(s): | Johnson, W. Hilton. Follmer, Leon R. |
Date: | 1989. |
In: | Quaternary Research. (1989.), Vol. 31(3) (1989) |
Abstract: | Presents evidence rejecting suggestion of H.A. Winters and others (ibid., Vol. 29, No. 1, 1988, p. 25-35) that Roxana silt in central and south-west Illinois is not related to glacial activity. Believes that valley-train source is most probable and urges continued consideration of Middle Wisconsinan glaciation in upper Great Lakes area. |
Notes: | Quaternary Research. Vol. 31(3) :319-331 (1989). |
Keywords: | 551.332.2 -- Drift, glacial. Deposits. 551.336 -- Ice ages. 551.79 -- Quaternary. E7 -- Glaciology: glacial geology and ice ages. (77) -- North central states. |
