Story: Sea floor geology

Solander Island

Solander Island

Solander Island lies north-west of Stewart Island and guards the western approach to Foveaux Strait. It is an extinct volcano with andesite rocks (similar to Mt Taranaki) that are 1–2 million years old. In New Zealand it is the only volcanic feature above water associated with the subduction of the Australian Plate beneath the Pacific Plate.
