The Influence of Fluvial Incision on the Lithospheric Stress Field: A Numerical Approach

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Erosion along large fluvial valleys transports important sedimentary volumes across continents over geological time, modifying the loads imposed on the lithosphere and inducing isostasy‐related subsurface stresses. This work presents numerical experiments with a visco‐plastic lithosphere aimed at understanding the distribution and evolution of

Impact of Mantle Velocity Uncertainty on Receiver‐Function Imaging of the Transition Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Seismological estimates of the 400‐km and 670‐km mantle discontinuities (d400 and d670) are crucial for understanding the thermochemical structure and dynamics of the mantle transition zone (MTZ). However, artifacts from using ray theory and uncertainties in mantle velocity structure can affect topographic mapping of these boundaries.
