The oldest rocks of Victoria Land are apparently banded gneiss and gneissic granite, which may be taken as Archaean.
Professor David and R. Priestley, the geologists of Shackleton's expedition, refer to Ferrar's and Prior's description of the foundation rocks, and state that according to their own investigations the foundation rocks consist of banded gneis, gneissic granite, grano-diorite, and diorite rich in sphene, besides coarse crystalline limestone as enclosures in the gneiss.
Low mountains and high hills that are characteristically cored by gneissic rocks.
The Northern Outer Piedmont (45f) is underlain mostly by deformed, deeply weathered gneissic rock that is intruded by plutons and veneered with saprolite; it is lithologically distinct from the Carolina Slate Belt (45c) and the sedimentary rock of the Southeastern Plains (65) and Triassic Uplands (45g).
The mountain chain is part of the Precambrian basement complex that comprises gneisses, gneissic granites, and metamorphosed sediments.
Inland these are replaced by gneisses, gneissic granites, and metamorphosed sediments of the Precambrian Basement Complex that forms part of the ancient massif.
The geology of the area comprises a mixture of gritty sandstones of the Karoo sediments, deep aeolian sands of the Pleistocene Kalahari system and gneisses, gneissic granites and metamorphosed sediments of the Precambrian basement complex.
The remaining rocks from Mount Betty are gneissic granite, partly very rich in dark mica, and gneiss (granitic schist); besides mica schist, with veins of quartz.
West of this line the rocks are chiefly Tertiary and Quaternary; east of it they are mostly Palaeozoic or gneissic.
There can be but little doubt that this vein is a capital example of hydrothermal fusion, whereby in original gneissic strata, at a moderate temperature and considerable depth, through the action of contained water, with the physical accompaniment of plication, a solution of the country rock has been accomplished.
