My favourite highlight: oceanward translation velocity of post‐salt sediments is highly dynamic. It is rapidly increasing to peak values during approximately 1 million years before slowing over tens of millions of years as the evaporite layer thins and welds onto the underlying syn‐rift sediments.

How is salt tectonics affected by salt rheology, rift tectonics, and sedimentation rates? ⚒️🧂

In this article of Zhichen Wang, we use cross-scale geodynamic models of lithosphere deformation, evaporite flow and surface processes: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Phase transitions control plume layering during Earth’s secular cooling Earth’s structure and dynamics have evolved quite a lot since its formation, and so has mantle dynamics and convection patterns changed along with it. It turns out that phase transition in certain man...

🌍 Earth’s mantle flow has changed over time.
Mineral phase shifts can stall plumes and reshape convection.
