An Express Method of gravi-magnetic Tomography for Estimating Reserves of Ore Occurrences Ferrous and Non-ferrous Metals
The rapid assessment of reserves of ore occurrences (iron ore, martitic, chromite ores and, in the long term - gold sulfide, polymetallic and other types of mineral raw materials) offered by the authors is based on the results of high-precision magnetic and gravimetric surveys. The use of the physical characteristics of ores and their host environment (density and magnetic susceptibility) in geotomographic technology makes it possible to explore the geological space in a reliable and reproducible way and to assess the prospect of exploration. To realize this task, the computer technology of anisotropic magnetic and density tomography of subsurface is used, which allows obtaining objective and reproduced geological information about the deep structure of the earth’s crust and its upper parts for the reproduction of reserves in the developed territories
