The contribution briefly summarizes the results of the study of magnetic minerals and palaeomagnetic properties of Pliocene and Pleistocene alkaline basalts and basanites, Neogene andesite and andesite porphyry of the Stiavnica stratovolcano (I-stage) and hornblende-biotite andesites of the Studenec Formation of the Central Slovakia. Magnetism carriers in the basalts are mostly titanomagnetites of a composition Fe_2.5Ti_0.5O₄–Fe_2.3Ti_0.7O₄. Pyroxene andesites and andesite-porphyry of the I-stage have been mostly propylized. They contain predominantly magnetic Fe-Ti oxides very near to magnetite-like mineral. Hornblende-biotite andesites of the Studenec Formation contain mostly haematite-ilmenite solid solutions. Magnetism carriers of andesitic rocks of both — the I-stage also the Studenec Formation are supposed to be of secondary origin. A. F. demagnetization tests were mostly used to consider palaeomagnetic stability of rocks, thermal tests were also rarely employed. Succession of the volcanic activity is presented on the base of the polarity of the stable RMP of volcanics using also a combination of radiometric ages of rocks with the polarity time-scale.
