    McElroy, C.T.; Rose, G. 1987 Geology of Beacon Heights, Southern Victoria Land, Antarctica. Scale 1:50,000. Wellington: Department of Scientific and Industrial Research. Miscellaneous series map / New Zealand Geological Survey 15 1 fold. map + 1 booklet

    Abstract: The stratigraphy of the Beacon Supergroup in the type area, the vicinity of Beacon Heights in the Quartermain Mountains, is presented as a ''benchmark'' descriptive work. Data and conclusions are essentially restricted to the type area. The Beacon Supergroup, which is largely flat-lying, rests unconformably on a Precambrian and/or lower Paleozoic granite basement; the erosional contact is the Kukri Erosion Surface. The supergroup consists of the Devonian Taylor Group (1100 m thick) overlain by the Upper Carboniferous to Triassic Victoria Group (750 m thick). The Taylor Group is a quartz sandstone sequence with red beds and contains seven formations: the Windy Gully Sandstone, Terra Cotta Siltstone, New Mountain Sandstone, Altar Mountain Formation (including the Ashtray Sandstone and Odin Arkose members), Arena Sandstone, Beacon Heights Orthoquartzite (including the Brawhm Sandstone, West Beacon Sandstone, and Farnell Sandstone members), and the Aztec Siltstone. Between the New Mountain Sandstone and the Altar Mountain Formation is the poorly developed Heimdall Erosion Surface. The Taylor Group is separated from the overlying Victoria Group by the Maya Erosion Surface. The Victoria Group is a deterogeneous sequence of glacial beds and carbonaceous and noncarbonaceous silty, sandy, and conglomeratic beds and contains four formations: the Metschel Tillite, Weller Coal Measures (including the basal Maya Arkose Member), Feather Conglomerate, and Lashly Formation. Between the Metchel Tillite and the Weller Coal Measures is the Pyramid Erosion Surface. Large scale intraformational folds occur in the Altar Mountain Formation, Arena Sandstone, and Metschel Tillite. Ferrar Dolerite of Jurassic age extensively intrudes the Beacon rocks, mostely as thick sills. A single small remnant of the Sirius Formation of Tertiary age crops out near Mt Feather. Surficial deposits include moraine material and talus
