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.
