The Moa Plate was an ancient oceanic plate that formed in the Early Cretaceous south of the Pacific–Phoenix Ridge. The Moa Plate was obliquely subducted beneath the Gondwana margin, and material accreted from it is now part of the Eastern Province of New Zealand. The plate was named in 2001 by Rupert Sutherland and Chris Hollis.
This is a list of tectonic plates on the Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). The composition of the two types of crust differs markedly, with mafic basaltic rocks dominating oceanic crust, while continental crust consists principally of lower-density felsic granitic rocks.Rupert Sutherland
