Taylor Group, Devonian

Fig. 10.11 Erosional remnants of the Beacon Supeigioup occur on the nunataks in the Rennrck basin and on its western edge along the polar plateau in northern Victoria Land. The formations are of Permian and Triassic age and belong to the Victoria Group. Rocks of the Devonian Taylor Group are not present in northern Victoria Land (Adapted from Gair et al. 1969)...

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)...

The sandstone is primarily composed of quartz grains some of which are well rounded and may have been derived from the Alexandra Formation of the Devonian Taylor Group. Grains of microcUne and sodic plagioclase occur throughout but deCTease in abundance toward the top of the formation. In addition, the sandstones contain lithic grains (schist and phyllite), biotite, muscovite, and pink garnet The matrix consists of sericite, chlorite, quartz, and calcite which are post-depositional.
