Glacial Diamictite

The unnamed glacial diamictite occurs in a down-faulted block of the western Lanterman Range in Fig. 10.12. It is about 250 m thick (McKelvey 1983  

McKelvey and Walker 1983) and includes glacial outwash as well as glaciolacustrine and fluvioglacial deposits (Laird and Bradshaw 1981 Skinner 1981). Collinson et al. (1986) and McKelvey and Walker (1983) correlated the glacial beds of northern Victoria Land with the Metschel Tillite of southern Victoria.

Fig. 19.3 The Cape Roberts Project drilled three holes through the sea ice about 16 km off the coast of southern Victoria Land at Cape Roberts. The cores are identified as CRP-1, CRP-2, 2A, and CRP-3 and were located close to CRP-1. The Cenozoic sediment at these sites dips away from the coast into the Victoria Land Basin. The cores consist of Oligocene to Miocene sediment composed of glacial diamictite interbedded with mudstone and sandstone. The sediment records the gradual cooling of the climate and increasing deposition of glacial sediments. CRP-3 bottomed in Devonian sandstone of the Beacon Supergroup (Adapted from Cape Roberts Science Team (1998) published in Terra Antartica vol. 5(1) 1-30, 1998)...

Fig. 19.8 The Meyer Desert Formation of the Sirius Group in the Dominion Range has a fine grained yellowish-tan matrix of sand, silt, and clay that encloses angular boulders of dolerite of the Ferrar Group and of sedimentary rocks of the Beacon Supergroup. This facies of the glacial deposits closely resembles the diamictite on Mt. Sirius in Fig. 19.5b. However, the section in the Dominion Range also includes thin bedded and well-sorted fluvial and lacustrine sandstones and sUtstones that formed in peiiglacial environments that existed between episodic advances of the East Antarctic ice sheet during the late Pliocene (Photo by G.
