Transformation of the Surface Structure of Marble under the Action of a Shock Wave

Resumo

The structure of marble fracture fragments formed after the destruction under the action of a shock wave have been analyzed by Raman, infrared, and luminescence spectroscopic techniques. It has been found that calcite I in the surface layer of fragments with thicknesses of about 2 μm is transformed into high-pressure phase calcite III. At the same time, concentrations of Mn²⁺, Eu³⁺, and other ions decrease to about onefourth of their initial values.
