Biomineralization as a Paradigm of Directional Solidification: A Physical Model for Molluscan Shell Ultrastructural Morphogenesis
Shell morphology as predicted by two-dimensional phase-field simulation under decreasing supersaturation. Concentration map: light gray –calcium carbonate rich, dark gray –organic-component-rich. Note that the prisms are formed from eight nucleation events: the borders between such areas are indicated by lines of organic-component-rich solid. Orientation map: black –fluid, different colors stand for different crystallographic orientations.
