Phase field modeling has been widely applied across various aspects of geological sciences, including the analysis of rock textures. Rock textures not only offer thermodynamic insights such as the temperature and pressure conditions at the time of formation but also preserve crucial information regarding their spatial and temporal evolution. There is a significant interest in understanding the physical parameters present during the formation of these textures within petrological studies. However, obtaining a precise analytical solution for equations that describe texture development, such as the Cahn-Hilliard equation, is nearly impossible without resorting to approximations. This challenge underscores the importance of computational methods, like phase field modeling, in deriving numerical solutions. Phase field modeling treats the concentration of each component within the system as continuous across a simulated field, providing a robust framework for modeling phase separation, texture formation, crystal growth, and kinetic phenomena in material science.
Recently, we have employed phase field modeling to investigate the development of textures resulting from spinodal decomposition in certain alloys and solid solutions. Through the simulation of elastic stress effects in coherent lamellar systems and the execution of 2D/3D phase field simulations, we have successfully delineated the dynamics of phase separation. These simulations offer insights into the parameters that dictate texture formation and the timescales of these processes. In this contribution, we aim to showcase the advantages of our novel approaches.
