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 tem porary observing sites across the West Carpathians (WCP). Induction re sponse data at 958 localities covering mainly the Central European are a were also collected and analysed. Components of transfer functions ( TF), moduli and arguments of corresponding induction vectors are analy zed for individual profiles. Pseudosections of induction parameters at profiles are used to visualize the period dependence of induction res ponse and computer generated contour maps of TF components define zone s of anomalous induction and their relation to large scale anomalies. Depths of anomalous field source are estimated by separating variation s into internal and external parts. Correlations among induction respo nse characteristics and the results of other geophysical investigation s are discussed.
