Weathering Stages Of A Tholeiitic Basalt (Dolerite), Queen Maud Mountains, Paul Andrew Mayewski
Weathering Stages Of A Tholeiitic Basalt (Dolerite), Queen Maud Mountains, Paul Andrew Mayewski

The sparsity of datable material and key horizons throughout most of the Transantarctic Mountains requires that much of the mapping and correlation of glacial deposits, especially moraines, be based primarily on qualitative techniques. One qualitative method is to characterize the degree of weathering of clasts covering these deposits (Behling, 1971; Calkin, 1971; Nichols, 1971; and Mayewski, 1975). Lacking, however, is a detailed understanding of the role and method of weathering. To help solve this problem, soil studies have been made by Claridge and Campbell (1968) in the Shackleton Glacier region and Everett and Behling (1968), Linkletter (1972), Behling (1971), and …
Glacial Geologic Investigation Of Upper Rennick Glacier Region, Northern Victoria Land, Paul Andrew Mayewski
Glacial Geologic Investigation Of Upper Rennick Glacier Region, Northern Victoria Land, Paul Andrew Mayewski
Earth Science Faculty Scholarship
The 1974-1975 field season was spent investigating the upper Rennick Glacier area (figure) for (1) the relationship between the glacial history of the study area and the glacial histories already defined for more southerly sectors of the Transantarctic Mountains, (2) the history and dimensions of former fluctuations of the east antarctic ice sheet, Rennick Glacier, and its tributaries, as recorded in glacial deposits, and (3) the significance of this area in paleoclimatic reconstructions of Antarctica and the world.

(From summary, pp. 105-106) In the central Transantarctic Mountains, the Sirius Formation consists of both a lower massive till and an upper assemblage of interlayered till and stratified lenses. Deposits of the Sirius Formation found in the McMurdo region contain only the lower massive till. The lower massive till of the Sirius Formation is thought to be a basal till because of extremely strong fabric, high concentration of faceted and striated pebbles, and heterogeneous particle sizes (clay to boulders). Fabrics observed in the basal till indicate that the ice that deposited the Sirius Formation, although displaying a much higher surface …
