Metamorphic Facies and Deformation Fabrics Diagnostic of Subduction: Insights From 2D Numerical Models

We developed a 2D numerical model that simulates the evolution of subduction in order to analyze which different metamorphic facies and deformation fabrics can be recorded within complex whether velocity influence their distribution. Regions with pressure temperature (P-T) conditions characteristic have been explored domains system verify existence associations may result as diagnostic specific areas at times. Distribution patterns strain rates relative also investigated they under conditions. Our results show three characterized by contrasting simultaneously observed regions complex, contrast widespread idea series are representative peculiar geodynamic scenarios, but agreement commonly coexistence contrasted P-T orogenic belts. In addition, we verified mylonitic develop more frequently high Pressure/Temperature (P/T) ratios, while coronitic fabric better preserved low-to-medium P/T ratios.
