Summary
The Lower Paleozoic rocks of North Victoria Land occupy a key position in any reconstruction of the New Zealand/Australian/Antarctic segment of Gondwanaland. To know the precise age of the Antarctic sequence and its geological history, is therefore an important component. Fieldwork was carried out to establish a stratigraphic succession through the thickest and most completely ... developed portion of the Bowers Group, to determine the environment of deposition of all parts of the succession and thus deduce its geological history, to seach for and collect fossils and fossil traces throughout the Bowers Group succession for paleontological dating, to collect suitable rock samples with the object of dating time of deposition or metamorphism of the sequence by radiometric means and to determine the relationship between the Bowers Group and adjacent and probably older successions (Wilson Group and the Robertson Bay Group). Rock samples were taken for radio metric dating.
