Abstract

This paper presents the results from the geomagnetic explorations conducted on the territory of the Lakavica depression (graben) which is located near Štip, in the eastern part of N. Macedonia. According the tectonic regionalization of Macedonia the Lakavica depression is located in the Vardar zone. It is relatively sinked block with orientation NW-SE, between the horst of Serta–Grdeški Mountains and the horst of Bučim block–Smrdeš. From the southwest, the Lakavica depression is limited with the horst of Serta–Smrdeški Mountains along the contrast normal (gravitational) fault. The horst of Bučim block–Smrdeš, which is characterized with very complex morphological structure, limits the Lakavica depression on the northeast. The geophysical–geomagnetic investigations were performed by three proton magnetometers. One was located on the base station and countinuously measured the daily variation, and with other two was measured total vector of the magnetic field. The magnetogram obtained from the magnetometer placed on the base station was used during the process of data processing for elimination of daily variation. The obtained results from the performed geophysical investigations confirmed that Lakavica is a depression sikned between two rised blocks
