“…If the interpreter wants to employ more sophisticated models which take into account the physical mechanism of the mineralization SP (Eskola and Hongisto, 1987;Furness, 1992), he/she may start with this model and use the calculated parameters of the dipole as initial values for a trial and error interpretation methodology. Reliable initial values may provide reliable final results.…”

“…Becker and Telford 1965;Parasnis 1970; Logn and Bolviken 1974;Kayal, Datta and Madhusudan 1982) suggests that it is fundamentally unsuited to model the mineral self-potentials inside the source body itself. Additionally, the simple source distributions employed by the model have also been criticized for being obscure in terms of the underlying electrochemical causation (Fitterman 1978;Sill 1983;Eskola and Hongisto 1987).…”

“…This dipole layer is taken to be the primary source of the physical model which will be referred to in future discussion as the double layer model for mineral self-potentials. Eskola and Hongisto (1987) present a numerical technique for computing the spontaneous mineralization potentials developed by their model. It involves the solution of an integral equation for the normal component of the current density along the surface of the source body.…”

Two methods for computing spontaneous mineralization potentials in the region external to the source body are reviewed. The first of these is a long‐established technique in which the causation is assumed to be a distribution of simple current source on the boundary of the mineralization. The second is a more recent technique which assumes a surface distribution of current dipole moment (double layer) along the boundary of the source body. The former technique is a special case of a more general spontaneous potential (SP) model in which the source is a density of current dipole moment (current polarization) distributed throughout the mineralization. As far as the potentials in the region external to the source body are concerned this current polarization can be simply related to an equivalent double layer source function, i.e. the potential discontinuity produced over the boundary of the mineralization by an equivalent double layer model. This simple relationship suggests an integral equation technique for the exact numerical solution of boundary value problems appropriate to the polarization model for spontaneous mineralization potentials. The technique is applied to exploring the justification of interpreting mineralization self‐potentials by the traditional approach.

“…Recent research (Eskola and Hongisto 1987;Furness 1992) has attempted to describe the mineralization SP field by taking into account the physical mechanism producing the SP effect. For this approach, a potential discontinuity on the surface of the ore body is the primary source for the SP field production.…”

A new method is proposed for the quantitative interpretation of SP field data produced by a polarized ore body and simulated by an inclined sheet. The theoretical concept is based on the study of the amplitude Spectrum. It is shown that the SP amplitude Spectrum is not continuous at zero frequency; this leads to the dip angle determination of the inclined sheet. It is also shown that the SP amplitude spectrum is practically nullified at a characteristic amortization frequency that depends on the depth of the polarized body. The maximum amplitude Spectrum value of the SP gradient is used to estimate the depth to the bottom of the polarized body.
