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)
A simplified map of the geological structures of Indonesia. The tectonics of Indonesia are very complex, as it is a meeting point of several tectonic plates.Indonesia is located between two continental plates: the Sahul Shelf and the Sunda Plate; and between two oceanic plates: the Pacific Plate and the Philippine Sea Plate.
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]
The northwards collision of the Australian plate with the Sunda plate (Sundaland plate, previously classified as part of Eurasian plate) has a maximum convergence velocity of 7.3 cm (2.9 in) per year ± 0.8 cm (0.31 in) per year at the Java Trench decreasing to 6.0 cm (2.4 in) ± 0.04 cm (0.016 in) per year at the southern Sumatra Trench.
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 South China Sea Basin is one of the largest marginal basins in Asia. South China Sea is located to the east of Vietnam, west of Philippines and the Luzon Strait, and north of Borneo. Tectonically, it is surrounded by the Indochina Block on the west, Philippine Sea Plate on the east, Yangtze Block to the north.
The Indo-Australian plate is or was a major tectonic plate. It is in the process of separation into three plates, and may be currently separated into more than one plate. It contains the continent of Australia, its surrounding ocean and extends north-west to include the Indian subcontinent and the adjacent waters.
