The micromorphology of amorphous silica pseudomorphs suggests that the volumepreserving replacement of nonsilie minerals proceeds via an interfacecoupled dissolution precipitation process. We conclude that colloid flow and postdepositional shearing create but also destroy natural photonic crystals. Contrary to previous studies, our results indie that purely .
