In the north is grey quartz andesite, a higher layer of the Ainslie Volcanics. In the north east is cream rhyolite from the highest layer of the Ainslie Volcanics. The Ainslie Volcanics were formed in the Silurian period. A layer of the Tertiary age pebbly gravels is around Anzac Parade, left over from when the Molonglo river was at a higher level.
