Fig. 5.1 The central Transantarctic Mountains include the area between the Nimrod and Beardmore Glaciers. The Byrd Glacier in the north and the Shackleton Glacier in the south are off this map. The basement rocks of this area crop out along the coast and are overlain by sandstones of the Beacon Supergroup farther inland. The only exceptions are the Miller and Geologist Ranges at the head of the Nimrod Glacier (Fig. 5.2) where the Nimrod Group is exposed (Adapted from Gunner 1976...

In the northern part of the central Transantarctic Mountains between the Byrd and Nimrod Glaciers, Laird (1963), Skinner (1964, 1965), and Grindley and Laird (1969) described the stratigraphy of the Byrd Group in terms of the formations listed in Table 5.1 ...

Fig. 10.13 The Beacon rocks in the Queen Elizabeth and Queen Alexandra ranges form high peaks in the central Transantarctic Mountains between the Nimrod and Beardmore glaciers. These rocks were deposited during the Devonian, Permian, and Triassic periods but the extent of the Devonian Alexandra Formation of the Taylor Group is limited as shown (Adapted from Barrett et al. 1986)...
