Grundriss der Augenheilkunde für Studierendebservatories supply sufficient accurate data, and their distribution on the Earth is very irregular. More importantly, the assumption implicit in deep conductivity determinations, that the conductivity is a function of depth only, breaks down because of near surface conductivity anomalies.

Geobotanik (Pflanzengeographie),n. This paper presents a review of some theoretical techniques for determining both the vertical and horizontal conductivity profiles of a region using a spatial distribution of observed electromagnetic fields at the Earth’s surface. Effects of shallow positioned anomalies upon a deep conductivity d

Crustal and Upper Mantle Structure of Stable Continental Regions in North America and Northern Eurole analysis using many record sections is described. The S wave velocity structure beneath the Canadian Shield is derived from constrained surface wave data. The thickness of the lithosphere beneath the Canadian and Baltic Shields is determined to be 95–100 km. The continental plate thickness may be

Temperature Profiles in the Earth of Importance to Deep Electrical Conductivity Models, and upper mantle rocks within the interval 200–1,000°C. It is shown how the knowledge of the temperature field can be used in the evaluation of the deep electrical conductivity pattern by converting the conductivity-versus-temperature data into the conductivity-versus-depth data.
