Frederick John Vine FRS (17 June 1939 – 21 June 2024) was an English marine geologist and geophysicist.He made key contributions to the theory of plate tectonics, helping to show that the seafloor spreads from mid-ocean ridges with a symmetrical pattern of magnetic reversals in the basalt rocks on either side.
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.
It focuses on geological processes, such as plate tectonics, that have changed the Earth's surface and subsurface over time and the use of methods including stratigraphy, structural geology, paleontology, and sedimentology to tell the sequence of these events.
Schematic diagram showing subduction system in conventional plate tectonics theory and divergent double subduction. Divergent double subduction (abbreviated as DDS), also called outward dipping double-sided subduction, [1] is a special type of subduction process in which two parallel subduction zones with different directions are developed on the same oceanic plate.

This debate is crucial to investigating when/how plate tectonics began on Earth. The Pilbara Craton along with the Kaapvaal Craton are the only remaining areas of the Earth with pristine 3.6–2.5 Ga crust. [1] The extremely old and rare nature of this crustal region makes it a valuable resource in the understanding of the evolution of the ...
The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago. Panthalassa , also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [ 1 ] was the vast superocean that encompassed planet Earth and surrounded the ...
