Quantitative geodynamics - Lithospheric processes, convection and global dynamics; Proceedings of the Symposium, Hamburg, West Germany, August 19, 1983
Abstract
A collection of papers dealing with quantitative geodynamics, devoted to the topics of lithospheric processes and convection and global dynamics, are presented. Lithospheric growth, thinning, and strength are discussed on the basis of thermomechanical approximations. Improved numerical finite element techniques are adopted in the study of continent-continent collisions and the relaxation of the lithosphere due to dip-slip deformation. The penetration of fluid bodies through a solid medium is considered, and flow problems of the lithosphere-asthenosphere system are approximated using an image system technique. Convective mixing and the related development of the fine mantle structure are studied, and improvements in numerical techniques for studying dynamical earth processes are discussed. Finally, constraints on the mechanical structure of the earth derived from quantitative polar motion modeling are addressed.
