How Climate, Uplift and Erosion Shaped the Alpine Topography

چکیده

Decades of scientific research on the European Alps have helped quantify vast array processes that shape Earth’s surface. Patterns in rock exhumation, surface erosion and topographic changes can be compared to sediment yields preserved sedimentary basins or collected from modern rivers. Erosion-driven isostatic uplift explains up ~50% geodetic rates; remaining reveals importance internal (tectonics, deep-seated geodynamics) external (glacial rebound, changes). We highlight recent methodological conceptual developments contributed our present view Alps, we provide suggestions how fill gaps understanding.

Erosion by an Alpine glacier.

Assessing the impact of glaciation on Earth's surface requires understanding glacial erosion processes. Developing erosion theories is challenging because of the complex nature of the erosion processes and the difficulty of examining the ice/bedrock interface of contemporary glaciers. We demonstrate that the glacial erosion rate is proportional to the ice-sliding velocity squared, by quantifyin...

Large Scale Terrain Generation from Tectonic Uplift and Fluvial Erosion

At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. This paper presents the first method in computer graphics that combines uplift and hydraulic erosion to generate visually plausible terrains. Given a user-painted uplift map, we generate a stream graph over the enti...

Colorado Plateau uplift and erosion evaluated using GIS

Study of the interaction between uplift and erosion is a major theme of our science, but our understanding of their interplay is often limited by a lack of quantitative data. A classic example is the Colorado Plateau, for which the starting and ending points are well known: The region was at sea level in the Late Cretaceous, and now, the deeply eroded land surface is at ~2 km. The path of the l...

Uplift, Shortening, and Steady State Topography in Active Mountain Belts

We present a tectonic, surface process model used to investigate the role of horizontal shortening in convergent orogens and the effects on steady-state topography. The tectonic model consists of a specified velocity field for the Earth’s surface and includes a constant uplift rate and a constant horizontal strain rate which varies to reflect the relative importance of frontal accretion and und...

Mechanics and erosion of basement-cored uplift provinces

[1] Basement-cored uplift provinces are often characterized by high-angle reverse faulting along preexisting crustal heterogeneities, which may greatly affect the mechanics of deformation and the coupling between erosion and orogenic structure. Herein we construct a coupled deformation-erosion model to understand the mechanics and erosion of mountain belts in which the spatial distribution of d...
