Abstract

Energy-variable synchrotron x-ray diffraction was applied to probe local structure in different kinds of aragonitic seashells with spatial resolution. All investigated specimens revealed lattice distortions of biogenic aragonite with respect to the geological mineral. The obtained data are analyzed in terms of residual strains induced by intercalating organic macromolecules.
