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 ...
The Wilson cycle describes the cyclicity in plate tectonics by forming supercontinents (Rodinia, Pangaea) and its breakup in hundreds of millions of years. It is named after the canadian geologist John Tuzo Wilson (1908-1993). Date: 1 November 2010, 01:00 (UTC) Source: File:Wilson-cycle hg.png: Author: Hannes Grobe 08:34, 21 January 2007 (UTC)
The Wilson cycle begins when previously stable continental crust comes under tension from a shift in mantle convection. Continental rifting takes place, which thins the crust and creates basins in which sediments accumulate. As the basins deepen, the ocean invades the rift zone, and as the continental crust rifts completely apart, shallow ...
The Wilson cycle of seabed expansion and contraction (associated with the Supercontinent cycle) bears his name, in recognition of his iconic observation that the present-day Atlantic Ocean appears along a former suture zone [8] and his development in a classic 1968 paper [9] of what was later named the "Wilson cycle" in 1975 by Kevin C. A ...

According to this newer version of the timeline which is a composite of Rivers 1997 and Gower and Krogh 2002, the Elzevirian orogeny occurs from 1240 to 1220 Ma, the Shawinigan occurs from 1190 to 1140 Ma and is no longer part of the Grenville cycle, the Ottawan (now 1090–1020 Ma) and Rigolet (still 1010–980 Ma) become phases which are ...
It is now in the decreasing phase of its cycle, and will reach its minimum around the year 11,800 CE. [15] Increased tilt increases the amplitude of the seasonal cycle in insolation, providing more solar radiation in each hemisphere's summer and less in winter. However, these effects are not uniform everywhere on the Earth's surface.
