Gondwana (/ ɡ ɒ n d ˈ w ɑː n ə /) [1] was a large landmass, sometimes referred to as a supercontinent.The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian Subcontinent.

New Zealand has been excluded from maps at the National Museum of Natural History in Washington, D.C. in the United States, in IKEA stores, on the map of the board games Pandemic [4] and Risk, on the map of the 2014 Nuclear Security Summit in which Prime Minister of New Zealand John Key participated, at a world map seal at the United Nations ...
In the Carboniferous, the new continent and another terrane, Armorica which included Iberia, drifted in from Gondwana, trapping Avalonia between it and the continent so adding Iberia/Armorica to Euramerica. [13] This was followed up by the arrival of Gondwana. The effects of these collisions are seen in Europe as the Variscan folding. In North ...
The natural history of New Zealand began when the landmass Zealandia – today an almost entirely submerged mass of continental crust with New Zealand and a few other islands peaking above sea level – broke away from the supercontinent Gondwana in the Cretaceous period. Before this time, Zealandia shared its past with Australia and Antarctica.
The Cretaceous is characterized by warm global temperatures caused by the high amounts of carbon dioxide and possibly methane greenhouse gases in the atmosphere. This caused a lack of permanent ice coverage in the polar regions, though the carbon dioxide level dropped between 115 and 66 million years ago (mya), possibly allowing some permanent ice cover.
GNS publishes a Map of New Zealand's Geological Foundations. [3] The main maps are the 1 : 250 000 QMap series, which will be completed as a series of 21 maps and booklets in 2010. [needs update] Low resolution versions of these maps (without the associated booklet) can be downloaded from the GNS site for free. [4]
The geology of New Zealand is noted for its volcanic activity, earthquakes and geothermal areas because of its position on the boundary of the Australian Plate and Pacific Plates. New Zealand is part of Zealandia, a microcontinent nearly half the size of Australia that broke away from the Gondwanan supercontinent about 83 million years ago. [1]
