Objective "The proposed project provide a comprehensive study of the chemical response of a host grain on volumetric changes connected with phase transition of inclusions in ultra-high-pressure rocks. The main goal is to investigate the effects of stress induced diffusion in a solid of uniform composition by means of an integrated approach including combination of conventional petrology methods with material science analytical techniques and numerical approaches. Though the interplay between stress and diffusion has been described in material science, the chemical response on stress induced during the solid phase transition has not been studied in geo-materials so far. The proposed hierarchic structure of observations on a wide range of length scales, from the thin section scale down to the nanometer scale will thus give a new and profound insight into the interplay of the kinetic processes, which control the microstructure and chemical evolution during solid phase transformation. The detailed analysis of these small scale processes in ultra high pressure natural samples will also offer valuable data for modeling larger scale processes in Earth interior. Moreover, as the diffusional relaxation modifies elastic state of the material which affects the mechanical properties of the phase, explicit formulation of relaxation kinetics and mass transport for natural, complex chemical system on small scale will provide insights relevant to problems in material science, ceramic industry as well as to radioactive waste disposal programs."
