Abstract
Abstract The Oscar Range in Western Australia’s Canning Basin features inliers of folded Paleoproterozoic quartzite, quartzitic conglomerate, and phyllite that formed islands during the Late Devonian. Undisturbed strata of the Pillara Limestone (Upper Devonian, Frasnian Stage) surround individual paleoislands that rise above the former seabed with a maximum topographic relief of 90 m. On average, the Mowanbini Archipelago (aboriginal name for the Oscar Range) lies 15 km off the granitic and metamorphic mainland represented by the Kimberley Block to the north. Devonian facies on outer rocky shores were studied at three localities near the southeast end of the Oscar Range. At the west end of the study area, a Devonian reef margin sits unconformably on Paleoproterozoic phyllite, but to the east, the reef is separated from rocky shores by a wide lagoon. Massive clast‐supported conglomerate and sandstone beds interfinger with backreef carbonates where the reef is closest to land. Across the lagoon 2.5 km eastw...
