Submillennial palynology and palaeoecology of the last glaciation at Taiquemo (similar to 50,000cal yr, MIS 2-4) in southern Chile

摘要

Stratigraphic palynology of core HE94-2B from a mire at Taiquemo (42.17 degrees S, 73.60 degrees W) on Isla Grande de Chiloe is one of the most closely sampled, continuous Pleistocene records in southern South America. Chronology of the 655-cm core that extends from Marine Isotope Stage (MIS) 4 through the Lateglacial is controlled by 27 finite radiocarbon dates. Sampled at 1-cm intervals, the high temporal resolution (mean similar to 85 yr cm(-1)) captures short-term palaeoecological changes and successional restabilization of plant communities.
