N2 - The paper presents new 40Ar/39Ar age determination of basalts from the Franz Josef Land archipelago. The obtained set of dates confirms the predominance of products only of Early Cretaceous age, which is also confirmed by results of paleomagnetic studies. Analysis of the entire set of geochronological data, taking into account information on their magnetic polarity, indicates that the interval of active magmatism occurred at the latest Barremian–Aptian and corresponds to the beginning of the Cretaceous Normal Superchron (C34n) at about 125 Ma. Significantly older age estimates are not related to the time of formation of the FJL basalts as a part of the High Arctic Large Igneous Province.
