Lead-zinc ores. Pavlovskoye Field, Novaya Zemlya.

Electrical exploration was carried out to solve geological, structural, engineering, geological, and hydrogeological problems at the lead-zinc mineral area.

The main method for solving these tasks is conducting field electrical exploration using electric sounding, in the ERT sounding induced polarization methods.

To assess the direction of fracturing of bedrock, an electrical survey was conducted using the method of cross Vertical electrical sounding (AVES).

Purpose of the work: identification and tracking of potential ore zones of the Utkinsky ore field based on a set of geophysical data.

Problem Statement:

- determine the geophysical features of potentially ore objects that are promising for Polymetal (copper-zinc) mineralization;

- identify promising anomalies for verification drilling operations.

Objects of this class are characterized by an increased content of sulfides (pyrite, chalcopyrite, sphalerite), which determined the composition of the complex of geophysical methods.

The complex of areal geophysical works included: electrical exploration by the method of induced polarization (IP) in the modification of the median gradient, magnetic exploration.
