Metamorphism & Electricity: Metamorphic Contributions to Electrical Phenomena in the Earth's Crust

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.
