Theoretical Basis for a Piezoelectric Effect in Rocksable practical value. A piezoelectric fabric is a property of polycrystalline materials which contain piezoelectric crystals oriented in some preferential manner with respect to some element of symmetry or some specific direction corresponding to an axis of infinite order.

The last few years have seen a relatively large amount of study of the electrical properties of rock samples and a need to organize the results of these studies has arisen. In"Electrical

Piezoelectric Effects in Rockseometric orientation of the electrical axes of quartz grains may be obtained for a few classes of rocks by x-ray diffraction methods. Positive results may be obtained by this method only in cases in which rocks are monomineralic fine-grained aggregates with a high degree of orientation of the crysta
