Using stress-activated electric conductivity in water ice doped with hydrogen peroxide as a model for stress-activated electric conductivity of igneous and high-grade metamorphic rocks due to the presence of peroxy defects, which when broken, createpositive-hole charge carriers. Blocks of pure H2O ice and H2O2–doped H2O ices, frozen at –20°C, will be stressed with piezo electric transducers(pzt) at one end to generate stress-activated electric currents flowing down the stress gradient. Pure H2O ice should produce no current or a small insignificant amount during rapid deformation or fracture. Stressing H2O2-doped H2O ices, however, should lead to 100-1000 times higher currents. These stress-activated currents are carried by defect electrons, generated by the break-up of the peroxy bonds of H2O2molecules embedded in the ice structure. These defect electrons are associated with the oxygen anion sub-lattice and known as positive holes. H2O2–doped H2O ices can be viewed as analogs to igneous and high-grade metamorphic rocks, which naturally contain peroxy defects, typically O3Si-OO-SiO3, and also produce positive hole currents when subjected to stres
