The work presents the first results on the anisotropy of magnetic susceptibility in Hooker Island basaltoids; this anisotropy is related to the direction of motion of the melt, the location of eruption centers, and the morphology of igneous bodies. The peculiarities of the primary magnetic fabric revealed correspond to a trap mechanism of formation of the Franz Josef Land igneous province and reflect the simultaneous effect of multiple small eruption centers. Earlier conclusions about the long-term (during the Early Jurassic-Early Cretaceous) multistage magmatism history have not been supported.
