Determining the geochronology of the Taylor Valley from the study of the geomorphology, lake levels, sediments and climatic events during the past 400,000 years
Entry ID: K009_1974_1975_NZ_2

Abstract: Fieldwork was carried out in the Taylor Valley over several seasons to determine the geochronology of the area.The lake beds and the geomorphology of a series of hummocks between the Suess and LaCroix Glaciers, were investigated for a carbonate rich sediment that was discovered here in a previous visit. Isotopic analysis suggested that the carbonates had been deposited from water of polar glacial ... View entire text

Figure 4: Startigraphic column of soil carbonate, Lake Henderson, Taylor Valley.
Interpretations from the geochemistry and dating of the deposits allow several events to be identified: a) 185,000-210,000 years BP and 95,000- 125,000 years BP. These are described in a paragraph.
