J. Tuzo Wilson Proposes Plate Tectonic Cycle
1966 · 20th Century
Canadian geophysicist John Tuzo Wilson published 'Did the Atlantic Close and then Re-Open?' in Nature, proposing that ocean basins undergo repeated cycles of opening and closing over geological time. Wilson argued that Caledonian and Appalachian mountain belts formed through the closure of a predecessor ocean which had occupied the same position as the modern Atlantic. This concept, later named the Wilson Cycle by Kevin Burke in 1975, linked continental drift, seafloor spreading, and mountain building into a unified tectonic framework.
