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.

Indo-Australian plate – Major tectonic plate formed by the fusion of the Indian and Australian plates (sometimes considered to be two separate tectonic plates) – 58,900,000 km 2 (22,700,000 sq mi) Australian plate – Major tectonic plate separated from Indo-Australian plate about 3 million years ago – 47,000,000 km 2 (18,000,000 sq mi)
Tectonophysics is concerned with movements in the Earth's crust and deformations over scales from meters to thousands of kilometers. [2] These govern processes on local and regional scales and at structural boundaries, such as the destruction of continental crust (e.g. gravitational instability) and oceanic crust (e.g. subduction), convection in the Earth's mantle (availability of melts), the ...
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]
Surface map of oceanic crust showing the generation of younger (red) crust and eventual destruction of older (blue) crust. This demonstrates the crustal spatial evolution at the Earth's surface dictated by plate tectonics. Earth's crustal evolution involves the formation, destruction and renewal of the rocky outer shell at that planet's surface.
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.
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
