Magnetotelluric and gravity modelling of crustal structures in the Northern Slovakia (Western Carpathians)

Popis výsledku v původním jazyce

Crustal structures in the northern part of Slovakia were interpreted based on magnetotelluric data with help of supplementary gravity information. Magnetotelluric measurements in northern Slovakia along the northern part of seismic profile 2T were modelled using new processing and inversion methods. Geoelectric model reveals the position and structure of the deep crustal tectonic units and identify major deep fault zones. Presented northern part of the model exhibits a significant influence of resistive complexes composed of Cadomian crystalline basement of European platform beneath Outer Western Carpathians conductive sediments of Flysch belt. The important contribution of the magnetotelluric method for the interpretation of crustal structures is the differentiation of high-resistivity and low-resistivity complexes, which can be interpreted in the southern part of the profile as inhomogeneities in the crust caused by tectonic superposition of granitoid and metamorphic complexes, as relics of crustal Hercynian tectonic structure. Young steep shear zones can be well identified by magnetotelluric method due to their conductive properties. In the gravity model we imaged denser structures of European platform and also overlaid flysch sediments, Klippen belt, Tatricum crystalline complex and Mesozoic carbonates.
