... The upper Paleozoic Whiteout Conglomerate, situated conformably upon the Crashsite Group and overlain conformably by the Polarstar Formation, may represent the entire period of Gondwanaland glaciation in West Antarctica. The formation, mainly massive diamictites, makes up about 1,000 m...

... detrital zircons were dated at ca. 480 Ma with major peaks at ca. 530 Ma and 500 Ma. Similar patterns are recorded in the Permian–Carboniferous Whiteout Conglomerate, with main components at ca. 650–500 Ma, and an absence of detrital zircons younger than Cambrian. The results, combined with stratigraphic...

... The 5,500+-m Paleozoic succession of the Sentinel Range includes the Heritage Group (Cambrian), the Crashsite Group (Cambrian and younger, including Devonian), the Whiteout Conglomerate (Carboniferous?), and the Polarstar Formation (Permian). All these predominantly clastic rocks were strongly...

.... It is clear, however, that despite considerable variation through the 1000 m thickness of the Whiteout Conglomerate, quartzite and granite boulders are always the most abundant and that quartzite always exceeds granite (Matsch & Okangas, 1992 , table 1 ). This compositional pattern is not seen...
