A detailed magnetostratigraphic study was carried out at the locality of Úhošť near Kadaň on the NE margin of the Doupovské hory volcanic complex. The majority of the samples had small viscous component that was possible demagnetized in the range 1 to 5mT or below 100°C. The primary components were pointing to the origin and were mostly interpreted in the range between 10 and 100mT or 100 to 560°C. The mean declination from all localities is 11.5 deg and inclination 53.9 deg. The parameter alpha 95 ranges between 2 and 10 degree. It's mean all lava flows has normal polarity. The major task is why all 13 localities have normal polarity although in the time range between the first and last volcanic event are several normal and reverse polarity periods.
