| Additional information | For map of selected surface volcanic features of the Tauranga Volcanic Centre. Much of the centre to the south west is buried under the Mamaku ignimbrite from the Rotorua Caldera which extends even to Matakana Island in Tauranga Harbour. There is one basaltic centre (gray) on the island. The buried approximate outline of the postulated Omanawa Caldera which likely grandfathered the Centre is in white. Brown shows the Waiteariki Ignimbrite that must have come from a supervolcanic eruption in the Centre. If you click on the map you will enable mouseover of volcano feature/wikilink. Characterised vents are black rectangles. Rhyolite fields from known vents is in red (geologically typed as Minden rhyolite) and andesite from the Otawa Formation is pink. Purple is the Papamoa Ignimbrite. The data comes mainly from Pittari, Adrian; Prentice, Marlena L.; McLeod, Oliver E.; Zadeh, Elham Yousef; Kamp, Peter J. J.; Danišík, Martin; Vincent, Kirsty A.
