Metamorphism generates electrical and magnetic phenomena, and is influenced by these forces. Information fundamental to their combined study is presented, including examples from microtectonics, crystal physics, geophysics, seismology, mineralogy and materials science. Applications for earthquake prediction, planetary science research, alternative energy and science education are included. Work on reported seismic electric signals is analyzed and summarized. Ten hypotheses related to earthquake mechanisms and prediction are presented, as well as eighteen recommendations for further study. Eight microtectonic deformation mechanisms are explored. Two hundred seventeen descriptions of minerals exhibiting ferroelectricity, pyroelectricity or piezoelectricity are presented, with quantitative data where known. Fifty-three of these are centrosymmetric, and explanations are given for their apparent violations of crystal theory. A comprehensive list of thirty-two mechanisms that generate telluric currents is also presented, as are some novel or inexpensive experimental techniques in crystal physics.
