APPLICATION OF THE INDUCED POLARIZATION METHOD IN SEARCH OF GOLD IN BLACK SHALE STRATA MUSHTINSKI ORE FIELD (NORTH CAUCASUS)

Abstract

The results of application of the pulse modification of the method of induced polarization (IP) within Mushtinski ore field when carrying out prospecting works on the areas of Malka-Mushtinski ore unit. Most optimal system of measurements, which allowed in a strongly dissected mountain relief and development carbonaceous shale to reveal the long, mineralized zones and mineral deposits stateformation different type, including a potential gold ore body is characterized. It is shown that the most effective to register the IP parameter is garagemate, which because of its integral nature in these conditions is a more robust parameter than the polarizability. Data for apparent resistivity (AR) and garagemate analyzed using the principal components method, when the 1st main component corresponds to an inverse relationship between the logarithm of the AR and garagemate and orthogonal her 2nd major components - direct. Thus, the anomalous region of 1-th components correspond to areas of prospective development of carbonaceous shale zones and watered faults, with a low resistance and high garagemate, 2nd components - prospective silicification zones and sulfide-vein mineralization, with high AR and high garagemate.
