Geologicko-geofyzikální modely zdrojů magnetických anomálií z vybraných oblastí Moravy

Abstract

The first part of the dissertation thesis summarizes the results of analyzes and interpretations of aeromagnetic data from a historical point of view, including their evaluation in combination with gravity data and available seismic reflection profiles and the compilation of geological models. The main part of the work contains the interpretation of geomagnetic anomalies from the Moravian part of the Bohemian Massif in the form of geophysical models. Subsequently, after supplementing with geological data from maps and deep wells, these models were modified into geological-geophysical sections. Geological evaluation of the magnetic field took place in three basic thematic areas focused on the area with the teschenite association rocks, the area with Tertiary basalts and the area with basic and ultrabasic rocks, mainly in the connection with the Moravosilesian Unit and Brunovistulicum. The actual processing of magnetic maps and modeling and interpretation of sources of magnetic anomalies were based on the using of modern software Oasis Montaj (Geosoft) with a modeling module - GM-SYS. At the end of the thesis, the contribution to practice is briefly stated.
