The Wilsonian cycle describes the cyclical opening and closing of ocean basins caused by plate tectonics, leading to the formation and breakup of supercontinents. This concept is significant in tectonics for understanding the long-term evolution of the Earth’s lithosphere, continental drift, and the processes driving the assembly and fragmentation of supercontinents.
