Map showing Earth's principal tectonic plates and their boundaries in detail. 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 km 2 (7.7 million sq mi)
The Izu–Bonin–Mariana (IBM) arc system is a tectonic plate convergent boundary in Micronesia.The IBM arc system extends over 2800 km south from Tokyo, Japan, to beyond Guam, and includes the Izu Islands, the Bonin Islands, and the Mariana Islands; much more of the IBM arc system is submerged below sealevel.
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
Burma plate – Minor tectonic plate in Southeast Asia; Cocos plate – Young oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America; Eurasian plate – Tectonic plate which includes most of Eurasia; Explorer plate – Oceanic tectonic plate beneath the Pacific Ocean off the west coast of Vancouver Island, Canada
The Shan–Thai or Sibumasu terrane is a mass of continental crust extending from Tibet into Southeast Asia sharing a similar geological history. The Shan–Thai terrane rifted from Australia in the Permian and collided with the Indochina terrane in the Triassic. [1] It extends from Malaysia, through peninsular Thailand, Myanmar, West Yunnan ...
A hypothetical lost oceanic plate called the Kshiroda Plate is supposed to have existed between the two subduction zones. It is now believed that this oceanic plate is actually a broken-off fragment of the above mentioned "Neo-Tethys oceanic basin". The bed of the Tethys sea lay on the Kshiroda Plate and was carried along with it towards Eurasia.
The Australian plate interacts at the southern and south-eastern border of the North Fiji Basin with the microplates of the New Hebrides already mentioned, as well as with the Conway Reef plate and the Balmoral Reef plates. To the west of Fiji the Australian plate interacts in the spreading centre of the Lau Basin with the Niuafo'ou plate and ...
