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)
GPlates enables both the visualization and the manipulation of plate-tectonic reconstructions and associated data through geological time: Load and save geological, geographic and tectonic feature data. Assign feature data to tectonic plates. Reconstruct feature data to past geological times. Query and edit feature properties and geometries.
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. 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 ...
Some fracture zones such as Chile and Valdivia make up large sections of the Nazca-Antarctic plate boundary. Map of the Chile Rise and its fracture zones in Nazca and the Antarctic plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown ...
The three plates which meet here are the South American plate, the African plate, and the Antarctic plate. The Bouvet triple junction although it appears to be a R-R-R type, that is, the three plate boundaries which meet here as mid-ocean ridges : the Mid-Atlantic Ridge (MAR), the Southwest Indian Ridge (SWIR), and the South American-Antarctic ...

Stretching for 4,300 km north-west from the Eltanin Fault System which intersects the Pacific-Antarctic Ridge to the Osbourn Seamount at Tonga and Kermadec Junction [6] is a long line of seamounts called the Louisville Ridge – the longest such chain in the Pacific [7] – thought to have formed from the Pacific Plate sliding over a long-lived center of upwelling magma called the Louisville ...
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
