Abstract

Summary

The study presents a mesostructural analysis of the tectonic deformations in the Tereblia-Rika Hydroelectric Power Station (HPP) region, situated within the Ukrainian Folded Carpathians. The area is characterized by complex nappe structures influenced by the Alpine orogeny, with active deformation zones linked to the Zakarpattian deep fault system.

Field investigations included the measurement of fractures, fault planes, and bedding orientations using a geological compass integrated into a tablet for high-accuracy digital data collection. Rose-diagram analysis identified dominant bedding orientations along NW-SE and NE-SW trends, reflecting regional structural controls. Fractures predominantly align along N-S and WNW-ESE directions, indicative of stress regimes related to regional fault activity. Fault orientations confirm NW-SE and WNW-ESE trends, consistent with major tectonic features of the region.

A Dieder Plot analysis of paleostress reconstructions revealed a combination of strike-slip and normal faulting, with principal stress σ oriented at 05°/237°, suggesting SW-directed compression. The high concentration of fracture orientations in the SE quadrant indicates active fault movements, with implications for geodynamic stability.

These findings are crucial for assessing geohazards, particularly for hydroengineering structures, and for predicting zones of potential deformation. Future research should integrate GNSS and InSAR data to refine stress-state models.
