摘要

Deep and surface mass fluxes in the Earth, driven respectively by tectonic and surface transport processes, determine the orogenic development and the evolution of topography. Vertical and horizontal motions, together with exhumation and sedimentation rates, are expressions of dynamic feedback relations between tectonic and surface processes. It is increasingly understood that inherited structures―memory of the lithosphere―play an important role at both scales. Since these processes interact and operate at a continuum of temporal and spatial scales, earth scientists of various disciplines increasingly use quantitative techniques to develop, test and validate geodynamic models. At the EGS 2001 meeting several symposia addressed rates and mechanisms of processes controlling erosion and tectonic movements, including the sedimentary archive. The contributions encompassed cross-disciplinary efforts from many directions: 1. quantitative constraints on rates (long-term and short-term) and length scales (distal and nearby) of denudation, erosion and deposition processes in different tectonic regimes and geological settings, 2. numerical modelling of non-linear dynamics of erosion and transport processes at geological time-scales, of interactions between erosion and tectonics and how these interactions may effect on erosion rates, and 3. analogue modelling of tectonic movements, erosion and deposition patterns.
