The use of micromorphology in examining the nature and history of Antarctic glacial sediments

There are two locations within south Victoria Land, Antarctica where
glacial sediments have been analysed using micromorphology. One is
Taylor Valley, where a discontinous linear moraine ridge at the snout
of the glacier is investigated so to understand whether the deposit is
a sublimation or melt out till, and what the diagnostic glacial
microstructures are respectively. The second location is the Allan
Hills, where an extensive distribution of Sirius glacial sediments can
be found. A number of glacial diamict samples are being analysed again
using the technique micromorphology so to help determine the
character of glaciation during the deposition of the Sirius glacial
sediments, as well as gauge an insight into whether more than one such
episode existed or not.
