Eastern margin of the Bohemian Massif is a geologically remarkable area, where three different orogenic cycles are meeting—the oldest, Cadomian, building a basement for younger cycles; a younger, Variscan; and the youngest, Alpine, covering the old

We present results of a classical global induction analysis of the geomagnetic variation data in the range of daily Sq variations, as well as for long period variations within the period range of about 8 to 400 days. The Sq data from 88 to 94 world o

Magnetotelluric directional analysis and impedance tensor decomposition are basic tools to validate a local/regional composite electrical model of the underlying structure. Bayesian stochastic methods approach the problem of the parameter estimation
