Abstract

The contact between the basement complex and the sedimentary sequence in the Royal Society Range is well exposed on both sides of Windy Gully along the main valley of the Taylor Glacier. The basal beds, consisting of cross-bedded sandstones, are overlain by 110 feet of alternating sandstones and dark fissile shales. Overlying these beds are massive sandstones of “normal” Beacon lithology. A 960-foot diabase sill has been injected 255 feet above the base of the massive sandstone unit. The section was measured for 390 feet above the top of the sill and probably overlaps with the lower portion of the Beacon section recently described by McKelvey and Webb.
