Summary

The stratigraphy of the Upper Carboniferous(?)-Lower Permian to Upper Triassic Victoria Group is remarkably similar over a wide area of the central Transantarctic Mountains. The Triassic Fremouw and Falla formations can be traced from the Queen Alexandra Range eastward across the Beardmore Glacier into the Shackleton Glacier area of the Queen Maud Mountains, affording a proposed revision of stratigraphic nomenclature. Sedimentologic data indicate alluvial plain deposition by low-sinuosity sandy streams on a muddy floodplain during Early Triassic time and by sandy braided streams during the Middle and Late Triassic. Paleocurrent and petrographic data provide supporting evidence for a bounding highland and contemporaneous volcanic source in West Antarctica.
