Abstract

The magnetic vertical component (ΔZ) anomaly map of Hungary was published by the Eötvös Loránd Geophysical Institute (ELGI) in 2006 to give a comprehensive overview on the locations of magnetized bodies in the country. This map, however, does not provide any information on anomalies in the area of Lake Balaton, the largest shallow lake in Central Europe. The reason is that earlier balance based magnetic surveys were not able to provide accurate data on the wavy surface of water. To fill the gap and map unknown anomalies in the lake area an integrated survey on the total magnetic field was carried out by the Department of Geophysics and Space Sciences of Eötvös Loránd University in the period of 2010-2016. The new map complements the national survey and implies small-scale magnetized bodies. The lake is located in the vicinity of the Bakony-Balaton Highland Volcanic Field (BBHVF). The magnetic anomalies in the western part of the lake are interpreted as subsurface magmatic rocks that are the southernmost members of this volcanic province. Anomalies in the central and eastern parts are aligned along the tectonic structures that were previously mapped by offshore seismic surveys. We suggest that these mostly linear features are the faint expression of tectonic structures in the magnetic field data.
