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.completedOceanographyIgneous and metamorphic petrologyAtlantic OceanCenozoicchemical compositionDeep Sea Drilling ProjectEuropehot spotsIcelandigneous rocksinclusionslavamantlemarine geologymineral compositionNeogeneNorth Atlanticocean floorspetrographyplate tectonicsPliocenepyroclasticsresearch vesselsReykjanes Ridgesamplesshelf-slope breakTertiarytuffvolcanic rocksWestern EuropeEnglishgeoscientificInformation-24.3000-24.000063.000063.3000
