Submarine ridge between New Caledonia and New Zealand
Topographic map of Zealandia showing the Norfolk Ridge
The Norfolk Ridge is a long
submarine ridge running between
New Caledonia and
New Zealand , about 1300 km off the east-coast of
Australia .
[1]
It is part of a complex region of ridges between the crust of the Pacific Basin and the continental crust of Australia. Little is known about the Norfolk Ridge; however, it generally lies about 2000 m below
sea level and consists of
Late Cretaceous
continental crust . It is part of
Zealandia , a submerged
continent that sank 60-85 million years ago.
