Inhalt:
The ensemble of manuscripts presented in this special volume captures the stimulating cross-disciplinary dialogue from the International Symposium on Deep Structure, Composition, and Evolution of Continents, Harvard University, Cambridge, Massachusetts, 15-17 October 1997. It will provide an update on recent research developments and serve as a starting point for research of the many outstanding issues. After its formation at mid-oceanic spreading centers, oceanic lithosphere cools, thickens, and subsides, until it subducts into the deep mantle beneath convergent margins. As a result of th
Anmerkung:
Based on papers presented at the International Symposium on Deep Structure, Composition, and Evolution of Continents held at Harvard University, Cambridge, Mass. Oct. 15-17, 1997.
