The Nimrod Glacier region has the most extensive exposures of basement rocks between south Victoria Land and the Scott Glacier region.

It is a prime target for study because of the thick siliciclastic and carbonate sequences, the rich biota in the carbonate beds, the post-orogenic coarse clastic sequences, the cross-strike extent of the.

State Geology. The Ross orogen of Antarctica is one of Earth's great Phanerozoic mountain belts. It is thought from igneous geochemistry, deformation patterns, and sedimentation history to be the result of late Neoproterozoic and early Paleozoic plate-margin convergence between paleo-Pacific oceanic lithosphere and continental lithosphere represented by the composite East Antarctic shield.

West of Terra Nova Bay and in the Beardmore Glacier region, lavas, tuffs and pyroclastic rocks occur, up to m thick, but elsewhere only thin sequences remain. Locally within the basaltic deposits, there are weathered zones with fossil soils and sediments containing Middle Jurassic fossils.

In contrast to the Victoria Land-Horlick region, basement rocks seldom crop out in this region, being deeply depressed beneath the sedimentary rocks.
