Topographic expressions of mantle dynamics in the Mediterranean
C Faccenna, TW Becker - Earth-Science Reviews, 2020 - Elsevier
The surface of the Earth is the ever-changing expression of the dynamic processes
occurring at depth and at or above its surface. However, our ability to “read” landscapes in …

Constraints on mantle viscosity from intermediate‐wavelength geoid anomalies in mantle convection models with plate motion history
The Earth's long‐and intermediate‐wavelength geoid anomalies are surface expressions of
mantle convection and are sensitive to mantle viscosity. While previous studies of the geoid …

Topography and gravity reveal denser cratonic lithospheric mantle than previously thought
The density structure of the cratonic lithospheric mantle (CLM) remains debated. We suggest
that one important reason for which many geodynamic studies favor neutrally buoyant CLM …
