Geoland
The land surface is a gently undulating till plain formed by retreat of the Wilson Piedmont Glacier; The Marble Point region is an old landscape, as evidenced by |
deposits of phillipsite, buried soils and oxidised gneiss, which have been covered by advances of the grounded Ross Ice Shelf; later ice retreat and glaciological |
features have been controlled by changes in the stranded Wilson Piedmont Glacier; the till mantle is patchy and dominated largely by locally occurring rocks |
