Abstract

The article presents the results of magnetotelluric sounding and magnetovariational profiling studies carried out in 2024 within the Precarpathian Trough to investigate the deep structure of the lithosphere searching for electrical conductivity anomalies that may be caused by the penetration of fluids from the crust and mantle into the upper layers of the geological section and may serve as an important source for all subsequent processes of oil and gas field formation. Synchronous modern magnetotelluric surveys were performed along the Bylychi—Hlyboka profile at fourteen observation sites, providing a space-time pattern of the distribution of geomagnetic variations and the electric field on the Earth’s surface. The experimental data were processed using the PRC_MTMV software package, and the response functions—tippers for geomagnetic variation periods ranging from 30 to 3400 s — and the curves of apparent resistivity (amplitude values and impedance phases) for periods ranging from 10 to 10000 s were analyzed. According to the results of the joint analysis of MT sounding and magnetovariational profiling data, the profile is divided into two parts. In the northern part the upper boundary of the conductor lies at depths of 20—50 km. It is located within the area of concentration of oil and gas fields of the Boryslav—Pokutskyi district and modern seismic activity. This northern part may represent a continuation of the sublatitudinal asthenospheric conductor identified in previous studies. The southern part is characterized by the presence of conductors at depths of about 20 km. The new geoelectric parameters described in the paper will be further used in constructing a three-dimensional model of the geologically complex Carpathian region.
