NON LINEAR CONDUCTION IN SULPHIDES
MSc Thesis 1974 (900kb.. pdf)
The thesis looks at non linear conduction in sulphide mineralisation and its applicability to exploration.
The measurement method involves dual frequencies, with a DC bias. The bias pushed the nonlineraity into the area where it may be possible to use the method in the field.
