We present mathematical modelling of the stationary geothermal field for the three-layered earth which includes a three-dimensional perturbing body below the first layer (over the halfspace substratum). The unperturbed temperature field corresponds t

The paper presents algorithm and numerical results for the boundary integral equations (BIE) method of the forward D.C. geoelectric problem for the three-layered earth which contains the prismoidal body with sloped faces in the second layer. This sit

The paper deals with some problems of the heat flow refractions on the subsurface structures with contrasting thermal conductivities. The qualitative and quantitative analyses of these effects were made on the selected structure configurations. Analy

We present a simple derivation of the interior and exterior gravitational potentials due to oblate spheroid and also its gravity field components by using the fundamental solution of the Laplace equation in oblate spheroidal coordinates. Application

Magnetotelluric measurements (MT) in the southeast (SE) part of MT–15 profile in the frame of CELEBRATION 2000 project identified a subhorizontal zone with higher conductivity in the depth of cca 2–6 km below the Tribeč Mts. surface. This zone i

We present mathematical modelling of the stationary geothermal field for the two-layered Earth which includes a three-dimensional perturbing body below the first layer (in the substratum). The body is in the form of 3D prismoid with sloping side face

We present analytical solution of the forward magnetometric problem for the oblate spheroid (rotational ellipsoid) as a causative body. The shorter semiaxis of the ellipsoid is supposed to be vertical to the surface of the earth. There is proved that

We present an exact analytical solution of the forward magnetometric problem for the perturbing body having the shape of the rotational prolate ellipsoid with the longer axis oriented vertically to the surface of the earth. The anomaly of ΔZ and ΔT

We present the exact boundary integral formulae for calculation of the geothermal anomaly due to a two dimensional body whose thermal conductivity is λT and its cross-section is bounded by the closed general polygonal contour. This body is buried in

New geomagnetic ground survey was carried out in years 2006–2008. The survey was accomplished under fair geomagnetic-activity conditions during the minimum phase of a solar activity cycle No. 23. The measurements of the geomagnetic field were redu
