ZEALANDIA

Recently, GNS Science, a New Zealand research institute, has published two new maps covering Zealandia’s tectonic profile and shape.

Zealandia is an almost entirely submerged mass of continental crust located in the southern Pacific Ocean that subsided after breaking away from Gondwanaland 83–79 million years ago.

The land mass may have been completely submerged by about 23 million years ago, and most of it (93%) remains submerged beneath the Pacific Ocean.

It is also known as Tasmantis due to its proximity to Tasman sea. Te Riu-a-Māui is another name for Zealandia.

The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995.

Political Divisions Under Zealandia Are:

New Zealand, New Caledonia, Norfolk island, Lord howe island group and Elizabeth and Middleton reefs.
