We present new paleomagnetic data for continental flood basalts (Siberian traps) obtained from cores of two boreholes in the northwestern Noril'sk area, within the Kharaelakh and Vologochan basins. Paleomagnetic measurements of lava and tuff samples from KhS-59 and SSV-19 boreholes allowed reconstructing and correlating the polarity patterns. Thus, multiple paleomagnetic anomalies (PA) have been discovered as short-term polarity changes in narrow intervals of the magnetostratigraphic section above the principal reversal at the boundary between the Ivakin and Syverma Formations. The most prominent anomalies are observed at the bases of the Morongo and Mokulai Formations. The samples from the anomalous intervals differ from those of other intervals neither in magnetic properties nor in mineralogy and magnetic grain sizes
