Middle Proterozoic landforms preserved at a disconformity in the Carrara Range Region, Northern Territory

The contact between the middle Proterozoic Mitchiebo Volcanics and Top Rocky Rhyolite, in the Carrara Range Region of the Northern Territory, is highly irregular and is interpreted as a disconformity. Sandstones in the Mitchiebo Volcanics were lithified and then eroded into a series of narrow ravines up to 120 m deep. Rhyolitic ignimbrite and lava blanketed and preserved the irregular surface. The preservation of the surface provides us with a rare glimpse of middle Proterozoic landforms.
