Anomalous induction zones in the Czech Republic in relation to large scale European anomalies

Induction response has been investigated at 57 field stations covering the Bohemian Massif (BM) and the Bruno-Vistulicum (BV), and at 93 temporary observing sites across the West Carpathians (WCP). Induction response data at 958 localities covering mainly the Central European area were also collected and analysed. Components of transfer functions (TF), moduli and arguments of corresponding induction vectors are analyzed for individual profiles. Pseudosections of induction parameters at profiles are used to visualize the period dependence of induction response and computer generated contour maps of TF components define zones of anomalous induction and their relation to large scale anomalies. Depths of anomalous field source are estimated by separating variations into internal and external parts. Correlations among induction response characteristics and the results of other geophysical investigations are discussed.
