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.
This article describes techniques; for a history of the movement of tectonic plates, see Geological history of Earth.. Plate reconstruction is the process of reconstructing the positions of tectonic plates relative to each other (relative motion) or to other reference frames, such as the Earth's magnetic field or groups of hotspots, in the geological past.
Tectonic plate reconstructions [ edit ] Consideration of the Earth system interactions requires complete tectonic reconstruction of all plate motions through time for the studied area, which are often not widely agreed upon, to create a framework within which Earth system interactions can be investigated.
Alan Gilbert Smith FGS (24 February 1937 – 13 August 2017) was an English geologist, stratigrapher, and pioneer of plate tectonic reconstruction. [ 1 ] [ 2 ] Education and career
As plate reconstructions have improved over the succeeding three decades since Morgan's original contribution, it is become apparent that the hotspots beneath the central North and South Atlantic and Indian Oceans may form one, distinct frame of reference, while those underlying the plates beneath the Pacific Ocean form a separate reference frame.

One of the smallest of Earth's tectonic plates, the Juan de Fuca plate is a remnant part of the once-vast Farallon plate, which is now largely subducted underneath the North American plate. In plate tectonic reconstructions, the Juan de Fuca plate is referred to as the Vancouver plate between the break-up of the Farallon plate c. 55–52 Ma and ...
Plate reconstructions for the time period based on the dates of the northwest–southeast trend and the older Line Islands are consistent with each other. [31] The oldest is a sample from one of the Northwest cluster at 98.1 Ma [ 2 ]
