Summary
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

Quality Data contained within the logistics report of the event submitted to Antarctica New Zealand, the following can be found:

Table 3: Summary of Antarctic U/Th dates (Sample number and location, U ppm, U234/U238, Age x 10-3, comments) - contact AntNZ for details.
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.
