On the characteristics of the early cretaceous platobasalt magmatism of Svalbard (Nordenskiold Land)

Based on the results of studies of basaltoid rocks of Western Svalbard (Nordenskiold Land), the features of their geotectonic position and distribution over stratigraphic complexes of the sedimentary cover are considered. Some characteristics of the geochemical composition of rocks are given. The age range of magmatism manifestation is estimated on the basis of radiological dating and in comparison with the arch. Franz Josef Land. In the context of the data obtained, considerations are made about the geodynamic conditions of the formation of the Barents Sea magmatic province.
