Abstract 

To study the deep structure of the Zakarpattia depression in 2023, modern synchronous magnetovariation studies were conducted along the Mali Heyivtsi - Tyachiv profiles at nine points and a spatial and temporal picture of the distribution of geomagnetic variations on the Earth's surface was obtained, which can be used to estimate the geoelectric structure of the region. The experimental materials were processed using the PRC_MTMV software package, which provides joint noise-protected estimation of induction parameters from synchronous recordings. Reliably obtained types for T from 19 to almost 6000 s. The analysis of the induction parameters indicates a stealthy both two- and three-dimensional distribution of the electrical conductivity in the near-surface region. With increasing periods, the types reflect the influence of the submeridional regional magnetovariation Carpathian anomaly and deep conductivity anomalies at the boundary of the Transcarpathian trough 40-60 km to 90-100 km of the Krosno cover and even deeper along the Porkulets and Duklyansky covers. Information on the existence of a deep conductor and its parameters should form the basis for quantitative interpretation and construction of a 3D deep geoelectric model.
