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.
Evidence of feather moulting in the Thermopolis specimen of Archaeopteryx is presented by Kaye, Pittman & Wahl (2020), who evaluate the implications of this finding for the knowledge of the origins of flight-related molting and flight; [293] the study is subsequently criticized by Kiat et al. (2021).
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.
Richard G. Gordon (born 1953) is an American geophysicist, known for his research on global tectonics, including global plate motions and palaeomagnetism.He is noteworthy for leading two global plate motion projects: NUVEL (Northwestern University Velocity) and MORVEL (Mid-Ocean Ridge Velocity).
Paleomaps are maps of continents and mountain ranges in the past based on plate reconstructions. Until the 1960s, paleomaps were not very satisfactory, since it was difficult to understand many quite distinctive features. For example, huge river deltas seemed to be associated with what must have been rather small drainage basins.
