    Geofizyczno-geologiczna interpretacja anomalii grawimetrycznych i magnetycznych w polskich Karpatach Zachodnich
    (Wydawnictwa AGH, 2007) Grabowska, Teresa; Bojdys, Grzegorz; Lemberger, Marek; Medoń, Zdzisław
    The study presents results of qualitative interpretation of gravity anomaly and anomaly of the total intensity of the geomagnetic field against the background of the geological structure of the central part of Polish Western Carpathians. Interpretation of gravity anomalies was preceded by an analysis of density of Carpathian flysch and substratum rocks. Maps of local anomalies showing various degree of details have been obtained by transformation of anomaly fields with appropriately selected parameters. The transformed gravity and magnetic anomalies were confronted with geological research data and magnetotelluric data. Convergence of negative gravity anomalies occurrence with the intermontane depressions Orava - Nowy Targ and Nowy Sącz and the zones of tectonic windows occurrence as well as positive gravity anomalies with positive magnetic anomalies and Precambrian substratum elevations, were demonstrated.
