Recently a paleomagnetic investigation, an analysis of magnetic minerals and radiometric (K/Ar) ages of the Pliocene-Pleistocene basalts of Central and Southern Slovakia has been performed. The analyses of the magnetic fraction of basalts revealed that the main carriers of magnetic properties are the titanomagnetites Fe_3-xTi_xO₄ with the compositional parameters x = 0.3–0.7. AF and thermal demagnetization tests were employed to consider the paleomagnetic stability of basalts. Stable remanent magnetization is thought to be linked to the more oxidized magnetic phase in basalts, comparing the results of the Curie temperature measurements with those of the thermal demagnetization tests of the rocks under consideration. The interpretation of the results is based mainly on the polarity of the stable remanent magnetization, using the combination of radiometric ages of the rocks and comparing it with the polarity intervals of the geologic time scale of Harland et al. 1989. Seven volcanic phases of basaltic activity were established. First volcanic phase: products of the Kalvaria Basalt Complex and volcanics of the Podrecany Formation. The former were emplaced during normal geomagnetic field (NF — 7.17–7.56 Ma), the latter arose in the course of reversed geomagnetic field (RF — in the interval, either 6.33–6.66, or 6.79–7.01 Ma). The second volcanic phase: (NF — 4.79–5.08 Ma, RF — 5.08–5.69 Ma and 4.48–4.79 Ma). The third volcanic phase: (NF — 2.48–2.92 Ma). The fourth volcanic phase: (RF — 2.09–2.48 Ma, NF — 1.65–1.88 Ma). The fifth volcanic phase (RF — 0.97–1.65 Ma). The sixth volcanic phase: (NF — either 0.0–0.72, or 0.91–0.97 Ma). The seventh volcanic phase contains lava flows of the nepheline basanites of the Putikov vŕsok Complex, which is the youngest volcanic body among of all volcanic complexes in the Western Carpathians. These basalts originated during the Brunhes epoch.
