Abstract
Abstract Cross-stratification in the Annear Formation (lower Bryneira Group) in northwestern Otago indicates sediment transport from west (c. 250°) towards east (c. 70°). Petrographic and chemical data indicate that these rocks are of mixed quartzo-feldspathic-volcanic provenance and are decidedly more silicic than overlying and underlying Bryneira volcanogenic terrigenous sediments. Compositional and stratigraphic similarities with Permian sediments of the Torlesse terrane are noted, and a common source area is tentatively suggested.
