Topographical and geological surveys and biology and soil sampling of the area between the Pennell and Tucker Glaciers to the Oates Land coast in north Victoria Land

An area roughly bounded by the Matusevich Glacier (157°, 30'E) in the west to the Tucker Glacier in the east and from 72° S north to the Oates Land coast was examined in reconnaissance fashion, including geological mapping and triangulation surveys. The southern limits mapped extended to the northern edge of the regions mapped in the 1962-63 season parties. Continuity of the geology was achieved between the western boundary of the Hallett geological map and the most eastern point, north of the Tucker Glacier. A total of 510 geological specimens were taken from 145 examined localities and used for age determination and bulk chemical analysis. The areas examined geologically include the Pennell Glacier to Arctic Institute Range, Central Rennick Glacier area, the east side of the Rennick Glacier to Lillie Glacier and from the Lillie Glacier to Tucker Glacier. More than 30 determinations of gravity were made during the course of the operation. 50 specimens of lichen, 14 soil and 10 moss samples were collected with precise positions located with reference to survey points. Biological observations while undertaking survey work was recorded also.
