Oscillatory Zoning in binary solid solution: a non-linear analysisTanja Mues and •Andreas Heuer — Institut für physikalische Chemie, Universität Münster, 48149 Münster

Oscillatory Zoning (OZ) is a phenomenon common to many geologically formed crystals. A model of OZ in a binary solid solution grown from an aqueous solution can be described by a two dimensional system of nonlinear partial differential equations, which were analyzed via linear stability analysis in the past. These results were compared with a numerical simulation of the full non-linear system. The non-linear terms give rise to new features in the structure formation by suppressing non-homogeneous modes. With a numerical and analytical Fourier analysis in the nonlinear regime we want to understand this behavior.
