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.[ 2] [ 3] [ 4]
