Investigations of petrography, mineralogy, and chemical composition of gases and fluids in tuffs and lavas were carried out on the samples dredged in the transition zone from the shelf and slope of Iceland to the Reykjanes Ridge. The samples were collected from the depths of 950-720 m during different expeditions of the R/V Akademik Kurchatov and Mikhail Lomonosov. Mantle ultrabasite inclusions were first recognized in the region of Iceland. It can be assumed that they are related to eruptive structures formed on the ocean floor during the Pliocene and are associated with the Iceland "hot" spot.
