Radiocarbon dates on deglaciation, Cordillera Central, northern Peruvian Andes / P.W. Birkeland, Donald T. Rodbell, S.K. Short.
Title: | Radiocarbon dates on deglaciation, Cordillera Central, northern Peruvian Andes / P.W. Birkeland, Donald T. Rodbell, S.K. Short. |
Author(s): | Birkeland, P. W. Rodbell, Donald T. Short, S. K. |
Date: | 1989. |
In: | Quaternary Research. (1989.), Vol. 32(1) (1989) |
Abstract: | Three radiocarbon dates, together with relative-dating criteria, place limits on deglaciation history of Manachaque valley. Ice retreated from late glacial maximum by 12,100 a BP. During ice retreat, numerous moraines were deposited throughout valley. Glacier cover was reduced to half by 9700 a BP and to <10% by 6450 a BP. Little or no ice by Early Holocene. |
Notes: | Quaternary Research. Vol. 32(1) :111-113 (1989). |
Keywords: | 551.336 -- Ice ages. 551.79 -- Quaternary. 551.791 -- Pleistocene. 551.794 -- Holocene. E7 -- Glaciology: glacial geology and ice ages. (85) -- Peru. |
