The UA Campus Repository is experiencing systematic automated, high-volume traffic (bots). Temporary mitigation measures to address bot traffic have been put in place; however, this has resulted in restrictions on searching WITHIN collections or using sidebar filters WITHIN collections. You can still Browse by Title/Author/Year WITHIN collections. Also, you can still search at the top level of the repository (use the search box at the top of every page) and apply filters from that search level. Export of search results has also been restricted at this time. Please contact us at any time for assistance - email repository@u.library.arizona.edu.

dc.description.abstractBasal 14C dates from a core of the mire at Puerto del Hambre (53 degrees 36'21"S, 70 degrees 55'53"W), located within the area of glaciation in Estrecho de Magallanes-Bahia Inutil, Chile, are no older than 14,455 +/115 yr BP. The 14C dates are on samples from which screening isolated autochthonous plant remains. Previous 14C dates of 15,800 +/200, 16,590 +/320, and 16,290 +/140 yr BP are from bulk samples collected from similar basal increments at the site during 3 separate, independent coring operations. The previous suite of 14C dates was suspected to be contaminated by older carbon in the light of chronological evidence, which indicates a 14C age of approximately 14,850 yr BP for glaciation elsewhere in southern Chile. Contamination by "infinitely old" carbon reworked from nearby Tertiary beds and redeposited at Puerto del Hambre is evidently the cause for the older 14C dates.
