In a series of measurements of electromagnetic radiation (EMR) from percussion-drilled Solenhofen limestone, nonoscillating signals (associated with electric depolarization) preceded by short oscillating signals (associated with crack propagation) were obtained. Depolarization is therefore assumed to be caused by stress relaxation around a propagating crack. Using the parameters of EMR signals, the polarization generating displacements of the Ca2+ ions in the calcite lattice caused by drilling were calculated. [ABSTRACT FROM AUTHOR] |
