Abstract

As geoelectric and electromagnetic methods play a significant role in geophysical prospecting in Hungary, it became necessary to solve the interpretation of complicated geological structures. The electromagnetic modeling laboratory built up in the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences in cooperation with several Hungarian institutions serves this purpose. To meet the modeling requirements an extremely wide frequency band modeling apparatus was to be planned. This involves in its present form instrument packages of modeling artifical frequency soundings using electric dipoles and for modeling some DC methods as well. The large quantity of the measured data and the requirements for parameter calculations made it necessary to use computerized data processing. This modeling apparatus has been used for investigations of high conductivity dykes related to faulting zones in the Transdanubian conductivity anomaly. We have used this apparatus in the bauxite exploration work of the Eotvos Lorand Geophysical Institute and for modeling frequency soundings above inhomogenous basement structures for the Geophysical Exploration Company. Future developments involve a plane-wave field generation as well as developing of magnetic sensing coil systems.-Authors
