Constraining depth and architecture of the crystalline basement based on potential field analysis - the westernmost Polish Outer Carpathians

The aim of this work was to establish the structure of a crystalline basement along the previously constructed regional cross-section located in the westernmost part of the Polish Outer Carpathians. The analysis of the gravity and magnetic data, additionally constrained by the borehole information, geological maps and seismic profile was carried out to anticipate the depth to the crystalline basement. Based on the qualitative interpretation, several basement-rooted faults were delineated that in some cases most probably affected the structural evolution of the Carpathians Thrust and Fold Belt. Moreover, along the entire cross-section, the basement seems to be located much deeper than previously anticipated. Lastly, the 2D potential fields modelling indicates that a continuous sedimentary cover, most probably represented by the Devonian and Carboniferous sequence or Miocene sediments of the Carpathian foredeep, may be expected below the Carpathians nappes along the whole cross-section length.
