The Mokohinau Islands are the surface expression of a largely submarine rhyolitic plateau and are a part of the Hauraki volcanic region offshore from the Northland Peninsula. Burgess Island contains basaltic to rhyolitic rocks. Fanal Island consists of a rhyolitic lava dome with an obsidian cap that is fission-track dated at 500,000 years ago (Skinner, 1986). Houghton (1994 pers. comm.) considers this date to be suspect.
