Quantifying glacial moraine age, denudation, and soil mixing with cosmogenic nuclide depth profiles

[1] Glacial boulders and soils on moraines are often dated to quantify the timing of glaciations and/or rates of chemical weathering in moraine chronosequences. A common assumption is that moraine crest erosion and soil mixing are unimportant. However, several studies suggest moraine denudation may be substantial. We evaluate the magnitude of moraine denudation and soil mixing in the Pinedale (...

Deglaciation and glacial erosion: A joint control on magma productivity by continental unloading

Glacial-interglacial cycles affect the processes through which water and rocks are redistributed across the Earth’s surface, thereby linking the solid Earth and climate dynamics. Regional and global scale studies suggest that continental lithospheric unloading due to ice melting during the transition to interglacials leads to increased continental magmatic, volcanic, and degassing activity. Suc...

The influence of glacial erosion on landscape evolution and basin morphology in the Bitterroot Mountains Montana

Erosion of Sognefjord, Norway

Sognefjord is formed by a combination of exploitation of rock structure and subaerial and subglacial processes. The fjord system follows zones of rock-structural weakness. Above sea level the landforms are due mainly to subaerial processes, and somewhat surprisingly not to glacial activity. Removal of erosive products and deepening of the fjord below sea level is due to glacial erosion.
