U012:
Plate Tectonics: 50 Years After the Revolution





Session ID#: 21880

Session Description:
Fifty years ago, the Earth Sciences were revolutionized by the discovery of plate tectonics, which subsumed the seafloor spreading and continental drift hypotheses. The geometrical framework of rigid plate tectonics on a sphere was presented for the first time in a talk at the 1967 AGU meeting, as noted in books such as Plate Tectonics, and The Continental Drift Controversy Vol. 4: Evolution into Plate Tectonics. AGU symposia commemorating the 10th and 25th anniversaries were well received, filling the largest meeting rooms. 50 years after a landmark event in the history of science is an appropriate time to look back and forward at the impact, including talks by early workers who developed plate tectonics and by current researchers, to see where plate tectonics has and has not taken us, and to emphasize improved solutions to problems solved by plate tectonics and to problems testing the limits of plate tectonics.
