2 Proposed Programme

2 Proposed Programme

The aims of the field work and subsequent research, as established by the PGSF grant in December 1995, were as follows:
  1. To collect data for a geologic and geomorphic map of the Sirius Group at Table Mt and Mt Feather.
  2. To obtain cores at least one metre long of the Sirius Group outcrops from at least three sites each at Table Mt and Mt Feather. Coring locations were to be selected on the basis of geomorphic mapping and previous sites where study samples were taken.page break
  3. To complete a comparative petrological study of the vertical core sequences taken through the Sirius. This includes determining the cause and relative timing of mineral dissolution and precipitation (mineral diagenesis). In addition, the stable isotope ratios of ice in pores and fractures will be measured. These will provide important clues about the post depositional history of the Sirius.page break
  4. To document the occurrence of diatoms through the vertical core sequence of Sirius. This will help determine the origin of the rare marine diatoms which may be crucial in determining the history of the East Antarctic ice sheet.
