The volume piezoelectric effect in polycrystalline rocks occurs if, in addition to preferred orientations of electric axes of crystals, these axes have orientational polarity. The present paper allows conclusions about some peculiarities of the processes and mechanisms leading to the formation of texturized rocks with piezoelectric properties. Information on the textures of rocks with peizoelectric activity was obtained by means of neutron diffraction, which gives the most complete information on the textures of large polycrystalline samples. These data, in combination with sample electrometric measurements, make possible the explanation of, for example, how the electric axes of quartz grains aligned in polycrystals. Three practicable mechanisms are suggested.
