During the Fifteenth General Assembly of the IUGG there will be four technical sessions devoted to a Symposium on Ocean Floor Spreading. This title is to be interpreted in a broad sense to include all aspects of science related to this major new theory of global tectonics.
Sessions or subsessions will be devoted to the following topics: Global Patterns, The Driving Mechanism, Oceans and Rifts, The Zones of Convergence, Selected Regions, and Selected Topics. The program will include a variety of invited review papers chosen for their merit, current interest and relevance to the central theme of the symposium. There are no plans for joint publication of the papers of this symposium.
