Search for Concealed Copper-Molybdenum Mineralization in Northern Kazakhstan with the Help of Electromagnetic Sounding Technologies and Induced Polarization (Ems-Ip)
2019
Summary Currently, more than 65% of world reserves of copper and about 60% of its world production, as well as more than 60% of molybdenum reserves and about 70% of its production occur in so-called copper-molybdenum porphyry deposits of hydatogenesis. These deposits are characterized by large accumulations of milling-grade ores, represented by systems of fine ore veinlets and small impregnations of sulfide ore minerals, among which chalcopyrite and molybdenite are widespread. The largest industrial deposits of this type are in Kazakhstan. The paper provides an assessment of the sensitivity of measured transients to changes in electrical resistivity and polarization, which makes it possible to separately determine the distribution of these parameters in the medium, as well as a comparison of the results of the inversion of pulsed electrical survey data with the geology of the area under study.
