Weakening Induced by Phase Nucleation in Metamorphic Rocks: Insights From Numerical Models

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.
Abstract Metamorphic transformations involve important changes in material properties that can be responsible for rheological alterations of rocks. Studying the dynamics of these changes is therefore crucial to understand the weakening frequently observed in reactive rocks undergoing deformation. Here, we explore the effects of reaction dynamics on the
