Quick Reference


Professor of geophysics at the University of Toronto, Tuzo Wilson was best known for his explanation, in 1965, of the transform faults which offset ocean spreading axes. His ideas were based on studies of linear magnetic anomalies and seismicity beneath ocean crust. He was the first person to use the term plates, and also invoked the idea of a hot spot to explain the evolution of the Hawaiian chain of islands. See wilson cycle.
