List of tectonic plates


This is a list of tectonic plates on 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.

Current platesEdit

Map showing Earth's principal tectonic plates and their boundaries in detail

Geologists generally agree that the following tectonic plates currently exist on Earth's surface with roughly definable boundaries. Tectonic plates are sometimes subdivided into three fairly arbitrary categories: major (or primary) plates, minor (or secondary) plates, and microplates (or tertiary plates).[1]

Major platesEdit

These plates comprise the bulk of the continents and the Pacific Ocean. For purposes of this list, a major plate is any plate with an area greater than 20 million km2.

  • African Plate – A major tectonic plate underlying Africa west of the East African Rift – 61,300,000 km2
  • Antarctic Plate – Tectonic plate containing Antarctica and the surrounding ocean floor – 60,900,000 km2
  • Eurasian Plate – Tectonic plate which includes most of the continent of Eurasia – 67,800,000 km2
  • Indo-Australian Plate – A major tectonic plate formed by the fusion of the Indian and Australian plates – 58,900,000 km2 often considered two plates:
    • Australian Plate – Major tectonic plate, originally a part of the ancient continent of Gondwana – 47,000,000 km2
    • Indian Plate – A minor tectonic plate that got separated from Gondwana – 11,900,000 km2
  • North American Plate – Large tectonic plate including most of North America, Greenland and part of Siberia – 75,900,000 km2
  • Pacific Plate – Oceanic tectonic plate under the Pacific Ocean – 103,300,000 km2
  • South American Plate – Major tectonic plate which includes most of South America and a large part of the south Atlantic – 43,600,000 km2

Minor platesEdit

These smaller plates are often not shown on major plate maps, as the majority do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km2 but greater than 1 million km2.

  • Somali Plate – Minor tectonic plate including the east coast of Africa and the adjoining seabed – 16,700,000 km2
  • Nazca Plate – Oceanic tectonic plate in the eastern Pacific Ocean basin – 15,600,000 km2[note 1]
  • Amurian Plate – A minor tectonic plate in eastern Asia
  • Sunda Plate – A minor tectonic plate including most of Southeast Asia
  • Philippine Sea Plate – Oceanic tectonic plate to the east of the Philippines – 5,500,000 km2
  • Okhotsk Plate – Minor tectonic plate in Asia
  • Arabian Plate – Minor tectonic plate – 5,000,000 km2
  • Yangtze Plate – Small tectonic plate carrying the bulk of southern China
  • Caribbean Plate – A mostly oceanic tectonic plate including part of Central America and the Caribbean Sea – 3,300,000 km2
  • Cocos Plate – Young oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America – 2,900,000 km2
  • Caroline Plate – Minor oceanic tectonic plate north of New Guinea – 1,700,000 km2
  • Scotia Plate – Minor oceanic tectonic plate between the South American and Antarctic Plates – 1,600,000 km2
  • Burma Plate – Minor tectonic plate in Southeast Asia – 1,100,000 km2
  • New Hebrides Plate – Minor tectonic plate in the Pacific Ocean near Vanuatu – 1,100,000 km2


These plates are often grouped with an adjacent major plate on a major plate map. For purposes of this list, a microplate is any plate with an area less than 1 million km2. Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere) like the Apulian, Explorer, Gorda, and Philippine Mobile Belt plates. There may be scientific consensus as to whether such plates should be considered distinct portions of the crust; thus, new research could change this list.[2][3][4][5]

Ancient continental formationsEdit

In the history of Earth many tectonic plates have come into existence and have over the intervening years either accreted onto other plates to form larger plates, rifted into smaller plates, or have been crushed by or subducted under other plates.

Ancient supercontinentsEdit

Supercontinent – Landmass comprising more than one continental core, or craton

The following list includes the supercontinents known or speculated to have existed in the Earth's past:

  • Columbia – Ancient supercontinent of approximately 2,500 to 1,500 million years ago

Ancient plates and cratonsEdit

Not all plate boundaries are easily defined, especially for ancient pieces of crust. The following list of ancient cratons, microplates, plates, shields, terranes, and zones no longer exist as separate plates. Cratons are the oldest and most stable parts of the continental lithosphere and shields are the exposed area of a craton(s). Microplates are tiny tectonic plates, terranes are fragments of crustal material formed on one tectonic plate and accreted to crust lying on another plate, and zones are bands of similar rocks on a plate formed by terrane accretion or native rock formation. Terranes may or may not have originated as independent microplates: a terrane may not contain the full thickness of the lithosphere.
