MARC recordMiddle Pleistocene age of the Nome River glaciation, northwestern Alaska / Darrell S. Kaufman, Robert C. Walter, Julie Brigham-Grette, David M. Hopkins.
| Title: | Middle Pleistocene age of the Nome River glaciation, northwestern Alaska / Darrell S. Kaufman, Robert C. Walter, Julie Brigham-Grette, David M. Hopkins. |
| Author(s): | Kaufman, Darrell S. Walter, Robert C. Brigham-Grette, Julie. Hopkins, David M. |
| Date: | 1991. |
| In: | Quaternary Research. (1991.), Vol. 36(3) (1991) |
| Abstract: | Presents results of ⁴⁰Ar/³⁹Ar laser-fusion analyses conducted on mg-quantity bulk subsamples of Minnie Creek lava that indicate presence of extraneous ⁴⁰Ar which rendered conventional K-Ar dates for larger bulk samples of same flow too old. Younger age for Nome River glaciation is further supported by new K-Ar age determination on lava flow at Lava Creek, where K-Ar whole-rock analysis of normally magnetized basaltic lava, that predates Nome River glaciation, yielded preliminary age of 564±66 ka BP. These results, coupled with amino acid epimerization and palaeomagnetic criteria, demonstrate that Nome River glaciation and subsequent shift from extensive to restricted glacial advances, is considerably younger than 800 ka. |
