Geology

The Chatham Islands are part of the now largely submerged continent of Zealandia.

They are the only part of the Chatham Rise above sea level. This means the Chatham Islands are far from the Australian-Pacific plate boundary which causes New Zealand's geology.

The rocks are a Mesozoic schist basement covered by marine sedimentary rocks. The rocks show sections of basalt from a series of eruptions. Volcanic activity has occurred multiple times since the Cretaceous. At present there is no active volcanism near the Chatham Rise.
