Software has been designed for forward and inverse modeling of natural self-potential (SP) fields which allows simulating the geoelectric patterns simultaneously for up to 29 sheet-like and prismatic electrostatically polarized conductors. The cross sections for a number of ore fields obtained by inversion with the new SPI-SV code (self-potential inversion, Siberian version) have been corroborated by later drilling and are consistent with reference geologic sections used in algorithm testing. SPI-SV simulation can provide high-quality assessment of mineral deposits and, furthermore, allows approaching global-scale investigation into the natural self potential of crust and mantle.
