The origin of intraplate alkaline mafic magmatism in continental shelves: lavas and xenoliths from the Upper Cretaceous volcanos of Mt Carmel Academic Article uri icon


  • Abstract Mafic alkaline rocks commonly occur in intra-plate settings, either in continental rifts or in areas with no extension, where they are interpreted as a manifestation of mantle upwelling above a hot spot. The origin of continental mafic alkaline magmatism may be very deep as indicated by the occurrence of xenoliths of garnet peridotite. Several intraplate magmatic events occurred in the Levant during Mesozoic times and were linked to the development of passive margins in northern Gondwana and to mantle plume rising beneath the African plate. Magma erupted during the late Triassic-early Jurassic (~ 200
