International audience; Frozen islands in the Lena River, Siberia, experience rates of fluvial thermal erosion exceeding 10m/year. The islands erode differentially, with rates of frontal retreat exceeding those on island sides. We define the erosion

Fluvial thermal erosion following ice breakups of the Lena River (Yakutia, Siberia) is a significant geomorphic process. During the initial stage of ice breakup, ice pushes up onto the river banks and produces large accumulations of ice and sediments

In Central Yakutia, frozen river banks are affected by a combination of thermal and mechanical erosion. Exceptional bank retreat of up to 40 m per year is observed. This results from ground thawing produced by heat transfer from the flow of water th

Magellan images have revealed areas with high topography on Venus like Maxwell Montes, interpreted as the result of a lithospheric thickening, associated to a global compressional stress regime. In addition to compressional structures, Maxwell Montes

SUMMARY This study reports the results of a 2-D numerical mantle convection model, featuring plate kinematics and non-vertical subduction. The main question we address is the combined eVects of plate velocities, convection intensity, and subduction d

Differentiation that occurs in zones of partial melting, forms less dense depleted mantle and basaltic crust. While the basaltic crust thickens, it transforms into denser eclogite. Typical values of Earth parameters are assumed to characterize Venus

Melting of the upper mantle and extraction of melt result in the formation of a less dense depleted mantle. This paper describes series of two-dimensional models that investigate the effects of chemical buoyancy induced by these density variations. A

The effects of ice content and water flow on thawing and erosion of non‐cohesive permafrost banks were investigated through laboratory experiments. A critical ice content was identified as associated with turbulent flows (20% and 80% for Reynolds n
